Vapor−Liquid Equilibrium and Liquid−Liquid Equilibrium of Methyl Acetate + Methanol + 1-Ethyl-3-methylimidazolium Acetate

Abstract

Vapor−liquid equilibrium (VLE) and liquid−liquid equilibrium (LLE) were measured for the ternary system of methyl acetate + methanol + 1-ethyl-3-methylimidazolium acetate ([EMIM][Ac]). The experimental LLE data were correlated by the NRTL model and the binary interaction parameters obtained from LLE were used to predict the ternary VLE, and the results agreed well with the experimental data. The results showed that the ionic liquid ([EMIM][Ac]) produced a notable salting-out effect, which enhanced the relative volatility of methyl acetate and methanol.
