a b s t r a c t 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 con- firmed by nuclear magnetic resonance (NMR). Vapor pressure of monoethyl succinate was measured and correlated with Antoine equation. Vapor-liquid equilibria at constant temperature were mea- sured for the binary systems ethyl acetate + monoethyl succinate, acetic acid + monoethyl succinate, and water + monoethyl succinate at 323.15 K, and ethanol + monoethyl succinate at 313.15 K. Binary parame- ters 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.
