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.
