Abstrakt: Isobaric vapor−liquid equilibria were determined at 101.3 kPa for the binary mixtures containing methanol + propyl acetate, methanol + isopropyl acetate, vinyl acetate + propyl acetate, and vinyl acetate + isopropyl acetate. The thermodynamic consistency of the experimental data was checked by means of a modified Dechema test and was satisfactory. The activity coefficients were correlated with the Margules, van Laar, Wilson, and NRTL models and the Wilson model with two suffix equations and the Wilson model with three suffix equations. The ASOG model was also used for prediction. The methanol (1) + propyl acetate (2) and methanol (1) + isopropyl acetate (2) systems show azeotropes at x1 = 0.922 and x1 = 0.890, respectively. Densities, excess molar volumes, refractive indices, and changes of refractive index on mixing of these mixtures were measured at 298.15 K and fitted to Redlich−Kister polynomials.
