Isobaric vapor−liquid equilibria for the binary systems benzene + methyl ethanoate, benzene + butyl ethanoate, and benzene + methyl heptanoate, at the pressure of (101.31 ± 0.02) kPa, have been determined using an all-glass recirculation still. 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.
