| Abstract: | Isobaric Vapor-Liquid equilibrium data at 0.0999MPa for C 8 aromatic hydrocarbon isomer +2-Propanol or t-Butanol systems were measured by a CP-I still.Pitzer-Curl-Tsonopoulos correlation for accounting the nonideal behavior of the vapor phase and liquid phase was used for calculating the activity coefficent of liquid phase.All the experimental data have been tested by the method proposed by Herington,the results show that the experimental data conform to demand of thermodynamic consistency. Composition and component's activity coefficient of liquid phase were correlated with wilson equation,The calculated values of the vapor composition are in rather good agreements with the experimental data. |
