Isothermal Vapor−Liquid Equilibria Measurements, Excess Molar Enthalpies, and Excess Molar Volumes of Dimethyl Carbonate + Methanol, + Ethanol, and + Propan-1-ol at 313.15 K

Abstract

Isothermal vapor−liquid equilibria (VLE), excess molar enthalpies, , and excess molar volumes, , have been measured for the binary mixtures dimethyl carbonate + methanol, + ethanol, or + propan-1-ol at 313.15 K and at atmospheric pressure. The three mixtures exhibit large deviations from ideality, showing an azeotrope at 0.14, 0.42, and 0.78 mole fraction of dimethyl carbonate, respectively. The VLE data were correlated by the Wilson equation and the appropriate parameters are reported. and values have been correlated using the Redlich−Kister equation by the method of least-squares.
