Liquid–Liquid Equilibria for Ternary Mixtures of Methylphenyl Carbonate, Dimethyl Carbonate, Diphenyl Carbonate, Anisole, Methanol, Phenol, and Water at Several Temperatures

Abstract

The ternary liquid–liquid equilibria (LLE) at atmospheric pressure of the following systems have been studied at several temperatures in stirred, thermo-regulated cells: water + anisole + methyl phenyl carbonate (MPC) at 308.15 K, water + methanol + MPC at 308.15 K, water + dimethyl carbonate (DMC) + MPC at 308.15 K, water + phenol + MPC at 318.15 K, and water + diphenyl carbonate (DPC) + MPC at 358.15 K. The experimental ternary LLE data have been satisfactorily correlated with the well-known two activity coefficient models: the Non-Random Two-Liquid (NRTL) and UNIversal QUAsiChemical (UNIQUAC). In addition, the distribution coefficients and the selectivity values of MPC for anisole, methanol, DMC, phenol, and DPC were derived from the tie-line data.
