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 323.15 K, and ethanol + monoethyl succinate at 313.15 K. 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.
► Monoethyl succinate (MES) was synthesized and purified. ► Vapor pressure of monoethyl succinate was measured. ► Vapor–liquid equilibria was measured and correlated with the NRTL equation. ► MES in binary systems with ethyl acetate, acetic acid, water, ethanol.
