ABSTRACT
Vapor-liquid equilibria (VLE) data for toluene + ethanol, toluene + isopropanol binary systems have been measured at (101.3, 121.3, 161.3 and 201.3) kPa using a vapor-liquid equilibrium recirculating still. The experimental data were checked with the Herington method, which showed thermodynamic consistency. The experimental VLE data were correlated with Wilson, NRTL and UNIQUAC activity coefficient models. The results show that the calculated values of vapor phase mole fraction and boiling temperature by the Wilson, NRTL and UNIQUAC models agree well with the experimental data. Furthermore, azeotropic VLE behaviors can be observed from the experimental data.
