In this work, isobaric vapor liquid equilibrium data for the binary mixtures of the isobutyl acetate + isoamyl acetate and isobutyl acetate + ethyl acetate were, measured using an all-glass dynamic-recirculation still equipped with a Cottrell circulation pump (Labodest VLE 602D). For the system of isobutyl acetate + isoamyl acetate the measurements were carried Out at 100 and 150 kPa, while for the system isobutyl acetate + ethyl acetate they were performed at 50, 100, and 150 kPa. Vapor pressures of the pure components were also measured to verify the performance and reliability of the equilibrium still, and data were correlated with an Antoine-type expression., The equilibrium data for the pure components were in agreement, with literature reports and the data for the binary solutions show a fairly ideal behavior. Binary parameters for nonrandom two liquid (NRTL) and universal quasichemical (UNIQUAC) equations were correlated with experimental data, and both models showed good agreement with experiments and, can be used for process design. It was found that, in the absence of ,experimental data, phase equilibrium in mixtures of acetates formed in the direct esterification of the fusel oil can be confidently predicted using the UNIFAC-DMD model or even the Ideal Model.
