ABSTRACT
Solubilities of isophthalic acid in ternary mixtures of acetic acid + water + benzoic acid were determined by static analytical method. The temperature range was from 292.55 to 372.10 K, the mass ratios of water to acetic acid were 0, 1:9, and 1:4, and the mass fractions of benzoic acid in initial solvent ranged from 0 to 20.1%. The experimental results indicated that solubility of isophthalic acid increased with the introduction of benzoic acid to the binary solvents of acetic acid and water, and that could be explained by Hansen's threedimensional parameters and like-dissolves-like rule. Then the experimental solubilities were correlated by the Non-Random Two Liquids (NRTL) model, and the model parameters were regressed. The values calculated by NRTL model showed good agreement with the experiment data.
