The activity coefficients of the solution were correlated with the Wilson, nonrandom two-liquid (NRTL), Margules, van Laar, and universal quasichemical activity coefficient (UNIQUAC) models through the fit of least-squares method. In addition, the VLE data of the ternary system were also predicted from these binary interaction parameters of Wilson, NRTL, Margules, van Laar, and UNIQUAC model parameters without any additional adjustment, which obtained the calculated vapor-phase compositions and bubble points compared with the measured values. The calculated bubble points with the model parameters of activity coefficients were in good agreement with the experimental data. The ASOG group contribution method also was used for prediction of the three binary systems. The thermodynamic consistency of the experimental VLE data was checked out by means of the Wisniak’s L–W test for the binary systems and the Wisniak–Tamir’s modification of McDermott–Ellis test for the ternary system, respectively.
