Solubility Behavior and Thermodynamic Analysis of Bisphenol A in 14 Different Pure Solvents
The solubility of bisphenol A in 14 different pure solvents (N,N-dimethylformamide, formamide, acetone, 1,4-dioxane, cyclohexanone, ethyl acetate, methyl acetate, acetonitrile, ethanol, methanol, 1-propanol, 1-butanol, 2-propanol, and 2-butanol) was measured at T = (273.15-313.15) K under atmospheric pressure using a laser dynamic method. The experimental data of bisphenol A were correlated by modified Apelblat equation, lambda h equation, nonrandom two-liquid model and Wilson model, and the fitting results showed that the modified Apelblat equation gave the best correlation with the experimental results. The thermodynamic functions of bisphenol A in 14 pure solvents, such as dissolution enthalpy (Delta H-mix), Gibbs energy (Delta(mix)G), and dissolution entropy (Delta S-mix), were obtained from the Wilson model. The results of the Delta(mix)G < 0 and Delta H-mix < 0 indicated that the dissolution process of bisphenol A in selected solvents was exothermic and spontaneous. The values of gamma(infinity)(1) and gamma(1) were not close, indicating that bisphenol A in selected solvent solution systems was nonideal.
