In this work, the isobaric vapor-liquid equilibrium (VLE) data for ethyl acetate + propyl acetate, ethyl acetate + propylene carbonate, and propyl acetate + propylene carbonate systems were measured at a pressure of 101.3 kPa by a modified Rose vapor recirculating-type equilibrium still. The experimental results show that no azeotrope was detected between the three binary systems. Two thermodynamic consistency tests of Herington and van Ness were employed to check the experimental data, respectively. The measured VLE data were correlated by Wilson, universal quasichemical, and nonrandom two-liquid models. The calculated root-mean-square deviation values of the equilibrium temperature and vapor phase mole fractions are not more than 1.07 and 0.0113, respectively. The relative volatilities were calculated and the deviations between the experimental data and Wilson model calculations were compared. All the correlated results are in good agreement with the measured data. Meanwhile, the binary interaction parameters were regressed by the three models for all the binary systems.
