Isobaric Vapor Liquid Equilibria for Binary Mixtures of Isoamyl Acetate + Ethyl Acetate at 50 and 100 kPa

Abstract

In this work new phase equilibria data for the system ethyl acetate + isoamyl acetate at pressures of 50 and 100 kPa are reported. The measures were carried out in the equilibrium apparatus FISCHER LABODEST VLE 602D, which is essentially a dynamic equilibrium cell equipped with a Cottrell recirculation pump. The quality of the experimental information was examined with the Wisniak point criteria because binary mixtures under study offer small deviations from the ideality. The nonrandom two-liquid and universal quasichemical activity models with symmetrical parameters were used to correlate experimental data, and both activity models show good correlation with experiments and can be used in distillation process calculations.
