Interest in aqueous systems containing alcohols and esters stems from the use of these compounds in food technology as aromas and extractants. In this work, liquid-liquid equilibrium (LLE) data are determined for the type I ternary systems ethyl acetate + ethanol + water and butyl acetate + ethanol + water, and the type II system ethyl acetate + butyl acetate + water at 25, 35 and 45°C. The experimental data are correlated by the NRTL and UNIQUAC equations using two approaches: a) system-by-system correlation; and b) joint correlation of the combined data for the three systems, affording common binary interaction parameters. Both models satisfactorily correlate the data. The binary interaction parameters obtained, in combination with those for further systems, will be useful for predicting the activity coefficients and LLE data of diverse multicomponent systems.
