From experimental data, the activity coefficients were calculated and satisfactorily correlated as a function of the mole fraction using the excess Gibbs energy model equations proposed by Margules, van Laar, Wilson, NRTL, and UNIQUAC. The predictive group-contribution models UNIFAC and ASOG were applied. The thermodynamic consistency of the data was verified with two point-to-point tests. The binary systems showed positive deviations from Raoult’s law, and no azeotrope was observed at this pressure. 2009-05-14 00:00:00 Methyl Ethanoate Binary Systems Benzene methyl ethanoate Butyl Ethanoate UNIQUAC butyl ethanoate methyl heptanoate activity coefficients NRTL ASOG mole fraction UNIFAC Gibbs energy model equations data van Laar systems benzene Methyl Heptanoate
