Abstract

Monoethyl succinate was produced by partial esterification of succinic anhydride with ethanol using Amberlyst 15® as catalyst. After separation and purification, the purity of monoethyl succinate was confirmed by nuclear magnetic resonance (NMR). Vapor pressure of monoethyl succinate was measured and correlated with Antoine equation. Vapor-liquid equilibria at constant temperature were measured for the binary systems ethyl acetate+monoethyl succinate, acetic acid+monoethyl succinate, and water+monoethyl succinate at 323.15K, and ethanol+monoethyl succinate at 313.15K. Binary parameters for the NRTL equations were obtained by fitting experimental data using the regression tool in ASPEN Plus® using the Hayden-O'Connell method for vapor phase fugacities. The model agrees reasonably well with the experimental data.
