Measurements, Correlations, and Modified UNIFAC Predictions of Isobaric Vapor–Liquid Equilibrium Data for the Binary System of Dimethyl Carbonate + Anisole at Different Pressures

In this work, isobaric vapor–liquid equilibrium (VLE) data for the binary system of dimethyl carbonate (DMC) (1) + anisole (2) at pressures of 33.33, 46.66, 59.99, 73.33, and 94.66 kPa were measured by using a Swietoslawski-type ebulliometer. The binary VLE data are correlated by the NRTL and Wilson activity coefficient models, and binary interaction parameters are determined by a using Nelder–Mead simplex optimization method. The correlated results are in good agreement with the experimental measured data, that is, liquid phase composition versus bubble point temperature for both NRTL and Wilson models. In addition to the correlated models, a group contribution-based modified universal quasi-chemical functional-group activity coefficient (UNIFAC)–Lyngby (LBY) model is used to predict the binary VLE data of the present binary system. The predicted results are in reasonably good agreement with the experimental data, indicating that the selected patterns of group interaction parameters are valid for the present system.
