    Abstract

    Liquid-liquid equilibrium data were measured for the ternary systems water + ethyl acetate + diethyl succinate and water + acetic acid + diethyl succinate at 298.15 K and atmospheric pressure. The reliability of the experimental data was confirmed using the Othmer-Tobias correlation. Vapor-liquid equilibrium data were also measured for the binary systems ethyl acetate + diethyl succinate at 313.15 K, acetic acid + diethyl succinate at 323.15 K and ethyl acetate + ethanol at 101.325 kPa. Binary parameters for the modified UNIQUAC and NRTL equations were obtained by fitting experimental and reported data using the regression tool in Aspen Plus®. The Hayden-O'Connell equation was used to represent interactions in the vapor phase. The models agree reasonably well with the experimental data and can predict reported azeotropic conditions.
