概要 Potentiometric pH measurements of 0.01 mol.kg(-1) aqueous solutions of hexanoic, heptanoic, and benzoic acids in 0.1 mol.kg(-1) NaCl media were performed using a flow-through electrochemical cell with two pressure-balanced hydrogen platinum electrodes. The dissociation constants of these carboxylic acids were determined on the basis of pH values measured at temperatures from (322 to 673) K and pressures of (23 and 30) MPa. The dissociation constants were consistent with the literature values determined from calorimetry, electrical conductivity, and potentiometry at temperatures up to 523 K. A simple Born model for describing temperature and pressure dependence of the dissociation constants was used to correlate the data.

概要 Continuous hydrothermal synthesis of Fe2O3 nanoparticles was carried out at 673 K and 30 MPa. Two types of mixers, a conventional T-type micromixer and a central collision-type micromixer (CCM), were used for the synthesis. CCM was newly fabricated on the basis of the concept for preventing heterogeneous nucleation induced on the inner wall of the mixer. Residence time and Fe(NO3)(3) molality of the starting solution varied from 0.1 to 1.0 s and 0.05 to 0.50 mol/kg, respectively. Effects of the mixer structure, the residence time, and the Fe(NO3)(3) molality on crystal structure, Fe3+ conversion, average particle size, and size distribution were discussed. CCM effectively worked for producing smaller Fe2O3 nanoparticles with narrow and monomodal distribution.

概要 Photo- and thermal reaction of p-substituted benzene diazo compounds (SBD) with [2.2.2]-cryptand (CRP) was studied by UV spectrum and degradation temperature (D.T.). Diazo cation of p-chloro benzene diazo compound (ClBD) was reacted with lone pair electrons of nitrogen atom of CRP by UV spectrum data. When CRP was added, photodecomposition rate of SBD with electron withdrawing-substituent (WSBD) and of SBD with electron donating-substituent (DSBD) were accelerated two and ten times larger than that without CRP, respectively. D.T. of WSBD with CRP in solid were lower than that without CRP, but D.T. of DSBD with CRP was similar to that without CRP. Photodecomposition rate of a diphenylamine-4-diazonium sulfate salt/formaldehyde condensate (DSR) / Polyvinyl alcohol (PVA) resist with CRP was 3 times higher than that without CRP. Diazo/PVA resist with CRP will be improved in sensitivity without decreasing thermal stability.

概要 Phthalaldehyde and 1,4-cyclohexanedione react in the 2: 1 molar ratio via a crossed aldol condensation in sub-and supercritical water to produce 6,13-pentacenequinone. The reaction conditions were optimized at 77% yield at 250 degrees C for 60 min with the starting molar ratio of 2: 1: 800 for phthalaldehyde, 1,4-cyclohexanedione and water, respectively. Whereas the initial rate of the reaction increased at higher pH, as suggested by earlier studies of the crossed aldol condensation of the two carbonyl compounds using a base catalyst in an organic solvent, the present results of successful reactions without the addition of any acid or base show the role of the increased solubility of the starting materials and the higher ion product in pressurized hot water. 6,13-Pentacenequinone was obtained as fine needles from the cooled reaction mixture just by filtration. Under similar conditions, 7,16-heptacenequinone and 5,12-naphthacenequinone were obtained in 46 and 70% isolated yields, respectively.

概要 The self-assembled monolayer film of trithiocyanuric acid (TCA) on evaporated silver films was characterized by using FT-IRAS and ab initio DFT calculation. Three hydrogen atoms in the most stable geometry of TCA tautomers were bonded to nitrogen atoms in the cyanuric ring. Observed IR bands for TCA in KBr disc at room temperature suggested that the TCA has a trithione form as same as in At matrix at low temperature as already reported. TCA on silver substrate gave rise to the IRAS bands corresponded to a less stable trithiol form. The calculated frequencies of silver-TCA complex that took a trithiol form with two silver atoms showed in a good agreement with the observed IRAS bands of TCA on silver substrate, on the other hand of silver-TCA complex that took a trithione form did not. The adsorption structure of TCA on evaporated silver film became obvious that TCA adsorbed to the Surface through the two sulfur atoms and changed to a trithiol form from trithione form.

概要 Hydrothermal synthesis of transparent conducting p-type delafossite CuAlO2 crystals from Cu(NO3)(2) and Al(NO3)(3) aqueous solution has been carried out at 400 degrees C and 30 MPa for reaction times of 10-30 min with a titanium alloy autoclave. NaOH and HCOOH were used to control metal oxide solubility and oxidation state of Cu, respectively. The method uses the specific property that supercritical water forms a homogeneous mixture with H-2 that is produced by hydrothermal decomposition of HCOOH. Phase and size of the obtained crystals were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. Molality of remaining metal ions was measured by atomic absorption spectrometry (AA). Effect of reaction time and molality of NaOH and HCOOH on the crystal phase was examined. Singlephase CuAlO2 crystal with the rhombohedral R3m structure was successfully synthesized at a yield of 99% from 0.1 mol/kg Cu(NO3)(2), 0.1 mol/kg Al(NO3)(3), 1.0 mol/kg HCOOH and 0.2 mol/kg NaOH aqueous solution for 30 min.

概要 Hydrothemal synthesis of gamma-Al2O3 nanoparticles obtained from aqueous Al(NO3)(3) solutions was carried out at 673 K and under pressures ranging from 30 to 40 MPa for 2 s using a flow apparatus. Effect of pressure and motality of HNO3 and KOH on crystal phase was examined. All products were a mixture of gamma-Al2O3 and AlOOH having crystallite sizes less than 18 nm. Weight ratio of gamma-Al2O3 to AlOOH in the products evaluated from TG showed a good correlation with pH at 673 K and increased from 0.17 to 1.16 with decreasing pH.

概要 A method has been developed for measuring the solubility of noble metal acetylacetonates by the direct injection of the supercritical carbon dioxide (scCO(2)) solution into a high pressure liquid chromatograph. We found the use of (1) reverse phase high pressure liquid chromatography (RP-HPLC) to separate the sample peak from the noise peak on chromatogram, and (2) a scCO(2)-philic eluent to eliminate the noise peak, to be effective. Using this improved method, we measured the solubilities of noble metal complexes of Pt, Pd, Ru, Rh and Ag acetylacetonates in scCO2 from 10 to 30 MPa at 313 K. Measurements were conducted with smaller amounts of samples (less than 0.1 g) and with shorter experimental times than by the standard dynamic flow method. The molar fraction y(2) was of the order 10(-5) to 10(-4) for Ru and Rh acetylacetonate, 10-5 for Pd and Pt acetylacetonate, and 10(-7) for Ag acetylacetonate. The solubility data for Pd, Pt, Ru, and Rh acetylacetonates were successfully correlated using the Chrastil model. (c) 2007 Elsevier B.V. All rights reserved.

概要 Continuous production of quinacridone nanocrystals via a hot compressed water (HCW) recrystallization method was studied using a flow-through experimental apparatus at 24 MPa at temperatures from 523 K to 573 K. Quinacridone crystals were dissolved in HCW and precipitation was initiated by mixing with room temperature water (RTW), which gave the nanocrystalline product. Polyoxyethylene lauryl ether and sodium dodecyl sulfate were found to be useful for reducing aggregation of the nanocrystals. The effects of temperature and flow rate on the size of the crystals were examined; increasing the degree of supersaturation caused crystals to decrease in size. Nanocrystals that had an average diameter of ca. 36 nm could be obtained at 573.8 K and 24 MPa at a flow rate of 10 g/min for HCW and 100 g/min for RTW. (c) 2006 Elsevier Ltd. All rights reserved.

概要 Ferrite nanoparticles from Fe(NO3)(3) and Me(NO3)(2) (Me = Ni, Cu, Zn) aqueous solutions could be synthesized continuously with a flow reactor at 673 K, 30 MPa, and 4 s residence time. The particles were characterized by TEM, XRD, and ICP to obtain sizes, crystal structures, lattice parameters, and Me/Fe molar ratios. Solid-solution nanoparticles of MeFe2O4 and gamma-Fe2O3 with a cubic spinel structure and an average particle size under 10 nm were obtained. Conversion of Fe 31 was more than 0.97 at the given residence time, and conversions of Me 21 increased from 0 to 0.62 with increasing residence time. The particle size increased with increasing residence time, and no significant difference in divalent cations was observed. The Me/Fe molar ratio in the obtained solid-solution nanoparticles of MeFe2O4 and gamma-FeO3 increased with increasing residence time and KOH molality. The Me/Fe molar ratio also increased in the order Zn < Cu < Ni at a given residence time, and this trend could be explained on the basis of ZnO, CuO, and NiO solubilities. The increase of the size and the Me/Fe molar ratio in the obtained particles with increasing residence time shows that, in the formation mechanism, primary solid-solution particles with low Me/Fe molar ratios probably nucleated and, after surface dissolution of the particles, dissolved Fe3+ recrystallized on the surface with incorporation of Me2+.

概要 Hydrogen solubility was measured for four equimolar binary solvent mixtures, benzene + toluene, cyclohexane + methylcyclohexane, benzene + methylcyclohexane and cyclohexane + toluene, and an equimolar quaternary, benzene + cyclohexane + methylcyclohexane + toluene, in the pressure range from 1.077 to 4.580 MPa at 303.15 K. The hydrogen solubility increased linearly with the pressure for all systems. The binary interaction parameters, in a mixing rule of Peng-Robinson (PR) equation of state, were determined for benzene + toluene and cyclohexane + methylcyclohexane from the vapor-liquid equilibrium data of literature, and that for benzene + methylcyclohexane and cyclohexane + toluene from the hydrogen solubility data in the binary solvent mixture. Using the optimized binary interaction parameters, PR equation well predicted the experimental data for the quaternary. (c) 2007 Elsevier B.V. All rights reserved.

概要 Solid-liquid equilibrium was measured for benzene+cyclohexane, traiis-decahydronaphthalene+naphthalene and cis-decahydronaphthalene+naphthalene under the atmospheric pressure in the temperature range from 226.69 to 353.14K. The apparatus was specially designed in this study. and it was based on a cooling method. The phase diagram with the complete immiscible solids was observed for the three systems, and the eutectic point was found at x(2) = 0.2709 and T-eu = 232.11 K for benzene + cyclohexane, x(2) = 0.9816 and T-eu = 241.98 K for trans-decahydronaphthalene + naphthalene, and x(3) = 0.9822 and T-eu = 225.74 K for cis-decahydronaphthalene + naphthalene, respectively. Hydrogen solubility was also measured for the two pure substances, trans-decahydronaphthalene and cis-decahydronaphthalene, and the three mixtures, trans-decahydronaphthalene + cis-decahydronaphthalene, trans-decahydronaphthalene+naphthalene, and cis-decahydronaphthalene+naphthalene, in the pressure range from 1.702 to 4.473MPa at 303.15K. Considering the solid-liquid equilibrium data, mole ratio of trans-decahydronaphthalene:cis-decahydronaphthalene was set to 50:50, and those of trans-decahydronaphthalene +naphthalene, and cis-decahydronaphthalene +naphthalene to 85:15. The hydrogen solubility increased linearly with the pressure following the Henry's law for all systems. The experimental solubility data were correlated or predicted with the Peng-Robinson equation of state [D.Y Peng, D.B. Robinson, Ind. Eng. Chem. Fundam. 15 (1976) 59-64; R. Stryjek, J.H. Vera, Can.

概要 Synthesis of Ni nanoparticles having an average diameter of 8.1 nm by reduction of NiO nanoparticles was carried out at 673 K. HCOOH was used as a reductant, which decomposes to CO and/or H2 at higher temperatures. NiO nanoparticles having an average diameter of 3.8 nm were obtained from Ni(NO3)2 + KOH aqueous solution by a flow-through supercritical water method at 673 K and 30 MPa. Effect of HCOOH concentration on particle size and saturation magnetization was investigated.

概要 Hydrothermal synthesis of metal oxide (AlOOH/Al2O3, CuO, Fe2O3, NiO, ZrO2) nanoparticles from metal nitrate aqueous solution was carried out at 673 K and pressures ranging from 25 MPa to 37.5 MPa with a flow-through supercritical water method. Size, phase and crystallinity of the obtained particles were characterized by TEM, XRD and TG, respectively. Effect of the difference of the metals in starting materials, pressures and concentrations on particle size and crystallinity was analyzed on the basis of supersaturation, which was evaluated by estimated metal oxide solubility. The result suggests that supersaturation should be set to higher than around 10(4) in this method to obtain particles under 10 nm in diameter. Further, crystallinity of the obtained particles was evaluated as weight loss through TG analysis. It was found that higher supersaturation decreased the crystallinity. This result can be explained that high supersaturation led to the inclusion of water molecules during the formation of particles.

概要 Supercritical water (SCW) has both the solvent power approximate to liquids and the transport properties common to gases. It is therefore expected as an excellent solvent for industrial waste treatment. In this study, various building materials were treated with SCW, and their morphological changes after treatment were observed. The effects of SCW treatment on the pore structure and compressive strength of cement concrete and mortar were also investigated.
In the range of this study, after SCW treatment, inorganic materials and organic materials can be recovered as solids and liquids, respectively. Under sub-critical and super-critical temperature and pressure conditions, compressive strength of mortar decreases, while the effective pore volume increases.

概要 The phase equilibria for the mixtures containing water, hydrocarbons and alcohols at high temperatures and pressures were predicted by a cubic equation of state with an excess Gibbs free energy (G(E)) type mixing rule using information from the conductor-like screening model for real solvents (COSMO-RS) method. The systems predicted were water + hydrocarbon, water + alcohol, hydrocarbon + alcohol binary systems and water + hydrocarbon + hydrocarbon and water + hydrocarbon + alcohol ternary systems. COSMO-RS method was used to calculate activity coefficients of the mixtures. UNIQUAC equation was adopted as an activity coefficient model in G E type mixing rule. The interaction parameters in UNIQUAC equation were determined with the activity coefficients calculated by COSMO-RS method. The modified Huron-Vidal mixing rule (MHV1) and a modified Soave-Redlich-Kwong (MSRK) equation of state were chosen as the G E type mixing rule and the cubic equation of state, respectively. Further, the MHV1 mixing rule was modified to apply in high temperature regions.
It was found that the prediction method proposed here can represent the phase behavior of the mixtures containing water, hydrocarbons and alcohols at high temperatures and pressures. The predicted results are compared with those calculated by a predictive Soave-Redlich-Kwong (PSRK) equation of state. The predicted results in this work are more accurate than those calculated by PSRK equation of state.

The phase equilibria for water+light alkane systems at high temperatures and pressures were predicted by a cubic equation of state. The predicted results were compared with those by Gibbs ensemble Monte Carlo simulation (GEMC) and were found to be superior.

概要 A high-temperature water (HTW) crystallization method was applied to produce size- and form-controlled organic nanocrystals without the use of any organic solvents. HTW and room-temperature water (RTW) were used as the extraction and cooling solvents, respectively. Nanocrystals are precipitated by mixing a high-temperature quinacridone aqueous solution in a newly developed micromixing unit with RTW from another line. Quinacridone nanocrystals having ail average diameter of ca. 9 nm as determined from transmission electron microscopy observations and ca. 83 nm from dynamic light scattering measurements were produced at 250.6 degrees C and 24 MPa with a flow rate of 10 g/min for HTW and 20 g/min for RTW. In addition, it was found that nanocrystals having different crystal sizes and forms could be obtained by changing the temperature and flow rate of RTW. This new method promises ail environmentally sustainable process for the continuous production of organic nanocrystals.

概要 Nickel particles were directly synthesized from 0.1 mol/kg nickel formate aqueous solution in supercritical water at 673 K and 30 MPa for 3-30 min with a titanium alloy autoclave. This method uses a specific property in which supercritical water forms a homogeneous mixture with hydrogen, which is produced by thermal decomposition of formate anion. In this environment, Ni2+ is easily reduced to Ni and Ni crystals precipitate. High-crystallinity Ni particles in sub-micrometer scale were obtained, and the hysteresis curve of the ferromagnetic crystals could be seen.

概要 A synthetic type apparatus was designed to measure hydrogen solubility in four pure aromatic or cyclic hydrocarbons, benzene, cyclohexane, toluene, and methylcyclohexane, and two equimolar binary mixtures, benzene + cyclohexane, and methylcyclohexane + toluene. The experimental temperature was 303.15 K, and the pressure range from 0.887 to 4.827 MPa. The hydrogen solubility increased linearly with the pressure following the Henry's law. The hydrogen solubility in benzene was smaller than that in cyclohexane. Similarly, the solubility in toluene was smaller than in methylcyclohexane. In the measurement for the mixtures, the mole ratio of benzene:cyclohexane and methylcyclohexane:toluene was set to 1:1. The hydrogen solubility in the equimolar mixtures was lower than that in pure cyclic hydrocarbon, cyclohexane or methylcyclohexane. The experimental solubility data in pure hydrocarbons were correlated with the Peng-Robinson (PR) equation of state using van der Waals one fluid mixing rule. Using binary interaction parameters in the mixing rule, the hydrogen solubility in the mixtures was predicted well.

概要 Gas permeation rates were measured for poly(4-methyl-1-pentene) (PMP) supported on an aluminum oxide film at temperatures from 298 to 423 K. The permeate gases used were nitrogen (N-2) oxygen (O-2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), and isobutene (iC(4)H(10)). The temperature dependencies of the permeabilities for N-2, O-2, CH4, and C2H6 were well correlated by Arrhenius-type equations. However, Arrhenius plots for C3H8, C4H10, and iC(4)H(10) had a concave shape, revealing minima for C4H10 and iC(4)H(10). To explain the permeation, a concentration-dependent diffusion equation and a cubic equation of state were used for the construction of a permeation model.

概要 The P-V-T-x relationship of three systems, pure carbon dioxide (CO2) and two binaries CO2 + butane (C4H10) and CO2 + isobutane (iC(4)H(10)), were measured with a constant volume method. The experimental temperature was set to be 360.00 K, and the range of pressure was from 1.0 to 10.5 Wa. For the mixtures, the mole fraction of either C4H10 or iC(4)H(10) was prepared to be less than 20.10 mol%. The data for CO2 obtained in this study agreed well with the literature. Experimental data were correlated with the Benedict-Webb-Rubin (BWR) equation of state, where the three constants for CO2 were redetermined in our previous work. The calculation using BWR equation with the Stotler-Benedict type mixing rules could correlate the experimental data of the two binaries well. The partial molar volume and the number of solvating molecules for C4H10 and iC(4)H(10) in the mixtures were calculated from the BWR equation. (C) 2003 Elsevier B.V. All rights reserved.

概要 Two types of experimental apparatus were designed to measure bubble point pressure for supercritical carbon dioxide (CO2) + lubricating oil. One was based on a synthetic method, and the other was on a recirculating method. An oscillation U-tube densimeter was also equipped with the recirculating type apparatus to measure the liquid density. Ensuring the reliability of the experimental data, bubble point pressure was measured for CO2 + decane (C10H22) at 344.3 K. The experimental data of the bubble point pressure and the liquid density were agreed well with the literature. Lubricating oil employed was polyalkylene glycol type one for refrigerators, commercially named PAG-1. The bubble point pressure and the liquid density were measured for CO2 + PAG-1 at 344.3 K. The experimental data were correlated with Peng-Robinson (PR) equation of state.

概要 A method using artificial neural network (ANN) was applied to estimate the vapor-liquid equilibrium (VLE) for the binary systems containing hydrofluoroethers (HFEs) and polar compounds. Our new estimation method is composed of three steps. In the first step, the sign of logarithm of activity coefficient (gamma) is estimated for each binary system using ANN, because it had been found that the binary systems containing HFEs show different thermodynamic behaviors depending on the sign for ln(gamma). In the second step, two sets of relation between liquid mole fraction and ln(gamma) are constructed: one held for the case of positive sign and the other held for that of negative sign. In the third step. vapor-liquid composition and equilibrium temperature are calculated using the estimated activity coefficient. In order to construct this new method, the isobaric VLE data of 18 binary systems including HFEs was used. As a result, our new method could estimate VLE with reasonable accuracy.

概要 Group contribution models such as ASOG or UNIFAC were known to be inaccurate in the prediction of infinite dilution activity coefficients (gamma(infinity)) for most of the systems containing water. To overcome the weakness inherent with the UNIFAC models, Zhang et al. (Fluid Phase Equil. 149 (1998) 27) have recently proposed a group-contribution-based model with mixture-type groups, where the mixture-type group is a hypothetical concept for taking into account the particular hydrophobic effects in aqueous organic systems. The proposed methodology has been proven to be applicable to alkane/water and alcohol/water mixtures in our previous study. In this work, the proposed method was further extended to the other classes of compounds, e.g. aromatics, ketones, acids, aldehydes, esters, ethers, nitriles and halogenated compounds. Compared to the conventional UNIFAC models, the proposed method demonstrates significant improvements in accuracy for various organic compounds in water mixtures.

概要 Isobaric vapor-liquid equilibria for 1,1,2,2-tetrafluoroethyl, 2,2,2-trifluoroethyl ether (CHF2CF2OCH2CF3) + alcohols, ketones, or esters systems were measured at 101.3 kPa. The alcohols used were ethanol and l-propanol, The ketone and ester components were 2-butanone and ethyl acetate, respectively. The measurements were made in an equilibrium still with circulation of both the vapor and liquid phase. The two binary isobaric systems composing of CHF2CF2OCH2CF3 and the alcohols exhibit minimum boiling azeotropes, The azeotropic points are found at x(1)(az) = 0.800 mole fraction and T(az) = 326.67 K for CHF2CF2OCH2CF3 (1) + ethanol (2) and x(1)(az) = 0.965 mole fraction and T(az) = 329.23 K for CHF2CF2OCH2CF3 (1) + l-propanol (2)1 respectively. The two binary systems of CHF2CF2OCH2CF3 (1) + 2-butanone (2) and CHF2CF2OCH2CF3 (1) + ethyl acetate (2) are both non-azeotropic. The experimental data for the binary systems investigated were correlated with activity coefficient equations. The nonrandom two-liquid (NRTL) equation yielded a good correlation of activity coefficients for the two systems of CHF2CF2OCH2CF3 with alcohols. The CHF2CF2OCH2CF3 (1) + 2-butanone (2) system is best correlated with the van Laar equation and CHF2CF2OCH2CF3 (1) + ethyl acetate (2) system best with the three-suffix Margules equation. The thermodynamic consistency of data was good according to the Van Ness and the Herington test.

概要 Isobaric vapor-liquid equilibria for bis(2,2,2-trifluoroethyl)ether + alcohols, ketones, or esters systems were measured at 101.3 kPa. The alcohols used are methanol, ethanol, 1-propanol, and 2-propanol. As the ketones 2-butanone was used, and used as esters ethyl acetate. The measurements were made in an equilibrium still [T. Hiaki, K. Kawai, Fluid Phase Equilibr 158-160 (1999) 979] with circulation of both the vapor and Liquid phase. The four binary isobaric systems of the CF3CH2OCH2CF3 and the alcohols form a minimum boiling azeotrope. The azeotropic points are found at x(1)(az) = 0.555 mole fraction and T (az) = 326.28 K for CF3CH2OCH2CF3 (1) + methanol (2), x(1)(az) = 0.716 mole fraction and T (az) = 331.90 K for CF3CH2OCH2CF3 (1)+ ethanol (2), x(1)(az) = 0.890 mole fraction and T(az) = 336.22 K for CF3CH2OCH2CF3 (1) + 1-propanol (2), and x(1) (az) = 0.777 mole fraction and T (az) = 334.16 K for CF3CH2OCH2CF3 (1) + 2-propanol (2). The two binary systems of CF3CH2OCH2CF3 (1)+ 2-butanone (2) and CF3CH2OCH2CF3 (1) + ethyl acetate (2) are both non-azeotropic. The experimental data of the binary systems investigated were correlated with activity coefficient equations. The nonrandom two-liquid (NRTL) equation yielded a good correlation of activity coefficients for four systems of CF3CH2OCH2CF3 with alcohols. Two systems of CF3CH2OCH2CF3(1) + 2-butanone(2) and CF(3)CH(2)OCH(2)CF3(1) + ethyl acetate (2) were best correlated with the three-suffix Margules equation.

概要 Isobaric vapor-liquid equilibria for two ternary systems, 2-methoxy-2-methylpropane (MTBE) + ethanol + 2-methyl-2-propanol and ethanol + 2-methyl-2-propanol + octane, and one binary system, ethanol + 2-methyl-2-propanol, have been measured at 101.3 kPa. The measurements were made in an equilibrium still with circulation of both the vapor and liquid phases. Both ternary systems and the binary system ethanol f 2-methyl-2-propanol do not form azeotropes. The three constituent binary systems of MTBE + ethanol, MTBE + 2-methyl-2-propanol, and 2-methyl-2-propanol + octane, which were measured in our previous work, are also not azeotropes. The other constituent system ethanol f octane, measured in our previous work, forms a minimum azeotrope. The experimental data for the binary systems were correlated with the nonrandom two-liquid (NRTL) equation. The NRTL equation yielded a good prediction of activity coefficients for the ternary systems from the parameters of the correlated binary systems.

概要 A small-capacity apparatus for vapor-liquid equilibrium (VLE) measurement was developed. The overall charge of the still with a provision for vapor and liquid recirculations was about 38 cm(3) of the solution. The performance of the proposed apparatus was tested by determining the VLE for the methanol + benzene system at 101.3 kPa. The results obtained were satisfactory. The isobaric VLE were measured for three binary systems, CH3OCH(CF3)(2) (1)+ methanol (2), CH3OCH(CF3)(2) (1)+ ethanol (2) and CH3OCH(CF3)(2) (1)+ 2-propanol (2) at 101.3 kPa using the proposed apparatus. All three binary isobaric systems form a minimum boiling azeotrope. The azeotropic points are x(1)(AZ) = 0.711 mole fraction and T(AZ)= 318.36 K for CH3OCH(CF3)(2) (1) + methanol(2) system, x(1)(AZ)= 0.859 mole fraction and T(AZ) = 322.21 K for CH3OCH(CF3)(2) (1)+ ethanol(2) system, and x(1)(AZ)= 0.918 mole fraction and T(AZ)= 323.44 K for CH3OCH(CF3)(2) (1)+ 2-propanol(2).

概要 A new approach is proposed by introducing mixture-type groups to the modified universal functional activity coefficient (UNIFAC, Dortmund) model for prediction of infinite dilution activity coefficients in highly nonideal aqueous solutions. The mixture-type group means a hypothetical one that appears in a particular type of mixtures only, and is considered here to account for hydrophobic effects specially taking place in a type of systems including water. Compared with the analytical solution of group (ASOG) model, the various UNIFAC models, and the correlation method of Pierotti, Deal and Derr (PDD), the new method has shown good accuracy. In addition, the new method can also improve considerably the predictive accuracy of mutual solubility, especially for systems with very small distribution ratios, in such cases the present group contribution models with common interaction parameters perform unsatisfactorily.

概要 The P-V-T relationship of three systems, pure carbon dioxide (CO2) and the two binaries CO2+n-butane (n-C4H10) and CO2 + i-butane (i-C4H10), were measured with a constant volume method. The experimental temperatures were set to be 304.65, 310.93 and 320.00 K for pure CO2 and 310.93 K for the two binary mixtures. The range of pressures was from 0.5 to 10.5 MPa. For the mixtures, the mole fraction of either n-C4H10 or i-C4H10 to CO2 was prepared to be less than 6 mol%. The data for CO2 obtained in this study agreed well with the literature values. The experimental data were correlated with several equations of state. The calculated values from Benedict-Webb-Rubin (BWR) equation of state showed the best reproducibility to the experimental data of pure CO2. The three constants in the BWR equation, c, alpha and gamma, were optimized with the experimental data of CO2. The calculated values using the optimized BWR constants with the Stotler-Benedict type mixing rule agreed well with the experimental data of the two binaries.

概要 Vapor-liquid equilibrium and liquid density were measured for the three binary systems water + tetraethylene glycol (TEG), ethanol + TEG, and 2-propanol + TEG at 298.15 K. The experimental apparatus employed for the vapor-liquid equilibrium measurement was based on a flow method, and that for the liquid density was a vibrating tube method. The activity of water showed the negative deviation from Raoult's law, while that of ethanol was almost proportional to the mole fraction of ethanol. For the 2-propanol + TEG system, the positive deviation could be seen. The liquid density for water + TEG showed the negative excess volume for the whole range of the mole fraction. The experimental data were correlated with the Peng-Robinson (PR) equation of state using the mixing rule proposed by Wong et al. and Orbey et al. The calculated vapor pressures showed good reproducibility for the three binary systems. The calculated density was not shown for the water + TEG system.

概要 Isobaric and isothermal vapor-liquid equilibria were measured for the 2-methyl-1-propanol + octane system at a pressure of 101.3 kPa and a temperature of 373.15 K. The measurements were made in an equilibrium still with circulation of both the vapor and liquid phases. The 2-methyl-1-propanol + octane system forms a minimum boiling azeotrope or maximum pressure azeotrope. The azeotropic data are x(1)(AZ) = 0.670 and T(AZ) = 376.58 K for the isobaric and x(1)(AZ) = 0.654 and P(AZ) = 90.67 kPa for the isothermal system. The activity coefficients of the system were best correlated with the nonrandom two-liquid (NRTL) equation for the isobaric and with the Wilson equation for the isothermal system.

概要 Isothermal vapor-liquid equilibria were measured for three binary systems of 1-butanol + octane at 373.15 K, 2-butanol + octane at 358.15 K, and 2-methyl-2-propanol + octane at 343.15 K. The measurements were made in a Rogalski-Malanowski type equilibrium still with circulation of both the vapor and liquid phases. Three binary isothermal systems form a maximum pressure azeotrope. The azeotropic data are x(1)(AZ) = 0.519 mole fraction and P(AZ) = 75.71 kPa for 1-butanol (1) + octane (2), x(1)(AZ) = 0.750 mole fraction and P(AZ) = 63.58 kPa for 2-butanol (1) + octane (2), and x(1)(AZ) = 0.968 mole fraction and P(AZ) = 61.18 kPa for 2-methyl-2-propanol (1) + octane (2). The activity coefficients of three binary systems were correlated with the Wilson, modified Wilson, nonrandom two-liquid (NRTL), and UNIQUAC equations.

タイトル Prediction of Infinite Dilution Activity Coefficents in Aqueous Solutions by Group Contribution Models. A Critical Evaluation and Improvement

概要 Based on an extensive database, the predictive accuracy of the ASOG and several UNIFAC-type models has been critically evaluated for infinite dilution activity coefficients in aqueous solutions. In general, all the models give rather poor results with mean relative deviations of 45-72% (except the cases where the relative deviations are higher than 100%), whereas the modified UNIFAC (Dortmund) performs well for most of higher polar compounds (e.g., ethanol, acetone, acetic acid) in water mixtures. The UNIFAC-LLE of Magnussen et al. may provide order of magnitude estimates for some lower polar compounds (e.g., aldehydes or 2-ketones with carbon number of 6-9), although it gives poor results for the higher ones. In the particular case of alkanes in water mixtures, the specially developed model of Hooper et al. provides comparatively fair results, but the predicted mean relative deviations of 36% are still large. In this work, an improved UNIFAC will be proposed by using mixture-type groups to account for the specially hydrophobic effects in systems including water, satisfactory results are obtained.

概要 Solubility and adsorption of high pressure carbon dioxide (CO,) to poly(styrene) (PS) were measured at 313.2 K and pressures up to 17 MPa using a quartz crystal microbalance (QCM) as a detector. Two kinds of PS film, made by dip coating (d-PS) and plasma polymerization (p-PS), were used as samples. The amount of adsorption onto both films was almost the same within the experimental range. The solubility to both films increased almost linearly against activity of CO2 up to unity, and that to p-PS was slightly higher than that to d-PS. Above unity, the solubility to p-PS film increased with the increase in activity. In contrast, solubility to d-PS sharply decreased near the unity and became a constant value.

概要 Experimental techniques for the determination of infinite dilution activity coefficients and their improvements are reviewed, Generally, the measuring techniques can be classified as the indirect and direct methods. The indirect methods include the extrapolations from vapor-liquid equilibrium data and calculations from the other thermodynamic data, such as liquid-liquid equilibrium data, gas-liquid partition coefficient data and so on. The direct methods include the gas-liquid chromatography (GLC) method, headspace GLC method, gas-stripping method, liquid-liquid chromatography method, differential ebulliometry method and differential static method, Also, the most extensively used gas-liquid chromatographic method can be divided into the stationary phase GLC, non-steady-state GLC and relative measurement GLC, A database of infinite dilution activity coefficients, which had been measured and reported by 96 literature sources of journals in the period from 1927 through 1995 for organic compounds in water and water in organic solvents, has also been presented. The database contains a total of 1469 pieces of data of infinite dilution activity coefficients ranging from 283.15 to 373.15 K. No database of infinite dilution activity coefficients for systems including water has been previously reported.

概要 Isothermal vapor-liquid equilibrium measurements were performed for the 2-propanol + water system containing poly(ethylene glycol) (PEG) at 298.15 K by a dow type apparatus. Three different PEGs whose molecular weights are 200, 1000, and 20 000 were employed, and their mass fractions in the liquid phase were up to 0.35. The volatility of water was reduced by the addition of PEG, and the azeotropic point of the 2-propanol + water system was changed to a higher mole fraction of 2-propanol. Activity coefficients of solvent were calculated by assuming the monodispersity of PEG. It was found that the activity coefficients of water were selectively decreased by the addition of PEG. These phenomena did not depend on the molecular weight of PEG.

概要 Isothermal vapor-liquid equilibria were measured using a still with the aid of a computer for control of the temperature and measurement of the total pressure. The measurements were made with circulation of both the vapor and liquid phases in a still of the Rogalski and Malanowski type (1980). The isobaric vapor-liquid equilibria were measured for the benzene + 2-propanol system at 10 1.3 kPa in order to test the consistency of results obtained with this still. Isothermal vapor-liquid equilibria were measured for the 2,3-dimethylbutane + methanol system at 313.15 K. The experimental data were correlated with the Wilson (1964) equation.

概要 Furfural formation from xylose is a typical successive reaction in which the furfural produced in a reactor disappears by side reactions such as polymerization and decomposition. In this work we investigated the effect of the extraction of furfural by supercritical CO2 on the selectivity and yield of the furfural. Furthermore, based on kinetic data we proposed a reaction model for furfural formation with or without supercritical CO2 extraction.
Judging from the experimental results, the recovery of furfural from the reaction mixture by supercritical CO2 extraction greatly improved the selectivity and yield of the furfural owing to the suppression of its side reactions. A simple reaction model could represent satisfactorily the change in furfural selectivity and yield with the xylose conversion for the reaction without supercritical CO2 extraction, while the model could explain fairly well the reaction accompanying supercritical CO2 extraction.

概要 To obtain fundamental data for the extraction and concentration of furfural produced in a reactor by using supercritical CO2, the isothermal high pressure vapor-liquid equilibria for two binary systems (CO2-water and CO2-furfural) and a ternary system (CO2-water-furfural) were measured in the temperature range from 343 to 421 K. Additionally, the experimental data were compared with results calculated by various equations of state. As a result, it was found that (1) the Peng-Robinson and Soave-Redlich-Kwong equations of state combined with the mixing rules proposed by Panagiotopoulos correlated the two binary systems satisfactorily and predicted the ternary system well, and (2) the furfural produced could be selectively extracted from the reactor and concentrated to 95 wt% by a new process proposed on the basis of a knowledge of the vapor-liquid equilibria.

概要 To measure the azeotropic point, a liquid-vapor ebullition type equilibrium still is developed. Vapor-liquid equilibria at 101.325 kPa are measured for the ternary azeotropic system benzene - cyclohexane - n-propanol, and the three constituted binary azeotropic systems. A method is introduced for graphical determination of the binary azeotropic point on the basis of experimental binary vapor-liquid equilibrium data. Also, a method is evolved for determination of the binary and ternary azeotropic points by using the extended Redlich-Kister equation applicable to the condition of constant pressure, and the azeotropic points are determined for three binary and one ternary systems.
