Isothermal Vapor−Liquid Equilibrium and Excess Enthalpy Data for the Binary Systems Water + 1,2-Ethanediol and Propene + Acetophenone

Abstract

Isothermal vapor−liquid equilibrium P−x data for the two binary systems water + 1,2-ethanediol and propene + acetophenone were measured by means of a computer-operated static apparatus. Additionally, excess enthalpy (HE) data for the binary system propene + acetophenone were measured with an isothermal flow calorimeter. The experimental data are presented using temperature-dependent interaction parameters for the UNIQUAC model which were fitted simultaneously to all measured data. The experimental results were compared with the data of other authors.
