Vapor Pressure and VLE Data Measurements on Ethyl Acetate/Ethanol Binary System at 0.1, 0.5, and 0.7 MPa

Abstract

The vapor–liquid equilibrium (VLE) of the ethyl acetate/ethanol system has been determined under isobaric conditions at 0.1, 0.5, and 0.7 MPa using a modified stainless-steel ebulliometer, which works continuously with the recirculation of both phases. The activity coefficients in the liquid phase are predicted using the ASOG model and different versions of the UNIFAC model; these values are quantified with respect to the experimental data, which are verified using the Van Ness point-to-point test.
