ABSTRACT

Solid-liquid equilibria for three organic binary mixtures of hexanedioic acid (1) + benzoic acid (2) (eutectic temperature TE = 378.17 K, eutectic composition x1E = 0.249), benzoic acid (1) + pentanedioic acid (2) (TE = 343.50 K, x1E = 0.402), and hexanedioic acid (1) + pentanedioic acid (2) (TE = 355.87 K, x1E = 0.205) were measured using differential scanning calorimetry (DSC). Simple eutectic behaviors for these systems were observed. The experimental results were correlated using the Wilson and nonrandom two-liquid (NRTL) activity coefficient models with satisfactory results.
