Vapor−Liquid Equilibrium and Mixing Properties of Methanol + Diethyl Carbonate and Vinyl Acetate + Diethyl Carbonate Systems

Abstract

Different mixing properties (speed of sound, density, and refractive index on mixing) of the binary mixtures methanol + diethyl carbonate and vinyl acetate + diethyl carbonate have been measured at 298.15 K and atmospheric pressure. Corresponding derived properties have been calculated by experimental data. Values of the physical properties were fitted to Redlich−Kister polynomials. The isobaric vapor−liquid equilibrium (VLE) experimental data at 101.3 kPa were satisfactorily tested for thermodynamic consistency by means of a modified Dechema test. Activity coefficients were correlated with Margulles, Van Laar, UNIQUAC, NRTL, and Wilson equations. The ASOG group contribution method was used for prediction.
