And also measured the binary systems of ethyl acetate + phenyl acetate, and diethyl carbonate + phenyl acetate at 373.15K.The experimental results exhibit no azeotropic behavior and positive deviations from Raoult’s lawfor each binary system. The thermodynamic consistency of the new binary VLE data has been confirmed by the point, area, and infinite dilution tests. The Wilson-HOC, the NRTL-HOC, and the UNIQUAC-HOC models were used to correlate each binary system measured in this work.Each model yielded satisfactory results.
