This study aims to determine the phase equilibria and mixture properties for the separation of reaction intermediates generated during the synthesis of non-phosgene diphenylcarbonate (DPC). The intermediates are based on dimethyl carbonate (DMC), phenol, methanol and anisole, etc. We analytically determined ternary liquid-liquid equilibria (LLE) for the following mixtures at atmospheric pressure and constant temperature: {water + DMC + anisole} at 313.15 K, {water + methanol + anisole} at 308.15 K and {water + methanol + phenol} at 328.15 K. In addition, density, refractive indices, excess molar volumes (V-E) and deviations in the molar refractivity (Delta R) of constituent binary systems at 298.15 K were determined. The experimental LLE data correlated well with two excess Gibbs free energy models: Non-Random Two-Liquid (NRTL) and UNIversal QUAsiChemical (UNIQUAC). V-E and Delta R data were correlated well with Redlich-Kister polynomial. (C) 2014 Elsevier B.V. All rights reserved.
