The quaternary solubility of acetic acid was decreased in the presence of diacetin and triacetin, due to more effective hydrogen bonds with acetic acid and supercritical CO2. In addition, it was observed that the solubility of polar diacetin molecules in non-polar CO2solvent increased by increasing...
Solubilities of acetylene in vinyl acetate and its mixture with acetic acid (1:1 molar ratio) were measured at temperatures from -15 to 0-degrees-C and at pressures from 20 to 100 kPa. Solubilities are characterized by mole fractions of acetylene and by Henry's constants. The temperature dep...
Solubility of benzoic acid, terephthalic acid and 2,6-naphthalene dicarboxylic acid in water, acetic acid, N,N-dimethyfformamide, N,N-dimethylacetamide, dimethyl sulphoxide and N-methyl-2-ketopyrrolidine were measured by dynamic method. The solubilities were calculated by UNIFAC group contribution me...

By using the laser-monitoring technique, solid-liquid equilibrium data of glutaric acid in cyclohexanol, cyclohexanone, their five mixed solvents and acetic acid were measured within the temperature range from 292.15K to 354.60K by dynamic method. Empirical formula and λ h equation were used to co...
