Abstract

Graphical abstract: Highlights: Isothermal (vapour + liquid) equilibrium (VLE) data were measured. Binary mixtures contain ethyl acetate, diethyl carbonate, phenyl acetate, diphenyl carbonate. No azeotrope formed in the systems investigated. The VLE data were correlated well with Wilson-HOC, NRTL-HOC, UNIQUAC-HOC models. Abstract: The isothermal (vapour + liquid) equilibrium (VLE) ( P – T – xi – yi ) was determined the binary systems of (ethyl acetate + diethyl carbonate) from T = (373.2 to 453.2) K, (ethyl acetate + phenyl acetate) at T = 373.2 K, and (diethyl carbonate + phenyl acetate) at T = 373.2 K, while the VLE ( P – T – xi ) of three diphenyl carbonate-containing binary systems was also determined experimentally at temperatures from (373.2 to 453.2) K. The experimental results show no azeotrope formation and near ideal solution behaviour for each binary system. These new VLE ( P – T – xi – yi ) data have been passed by the point, area, and infinite dilution thermodynamic consistency tests. The Wilson-HOC, the NRTL-HOC, and the UNIQUAC-HOC models were applied to correlate the VLE results and the optimal values of the model parameters have been determined through data reduction. Comparable results were obtained from these three models.
