ABSTRACT
The solubilities of decanedioic acid in binary solvent mixtures consisting of ethanol + cyclohexane, ethanol + n-heptane, and ethylene glycol + water were determined by a dynamic method over the temperature range of 291 to 352 K. The solubility in mixed solvents was slightly greater than both of the pure components (the synergistic effect) at some compositions in the systems of decanedioic acid + ethanol + cyclohexane or n-heptane. The measured solid-liquid equilibrium (SLE) data were correlated with the Wilson model and the non-random two liquid (NRTL) model. Furthermore, the relation between the synergistic effect and the azeotropy character of the mixtures of solvents was discussed.
