【Abstract】 Isobaric vapor-liquid equilibrium data at 12.666kPa for four systems(t-butanol+ethyl benzene,t-butanol+o-xylene, t-butanol+m-xylene,t-butanol+p-xylene)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 coefficient of liquid phase.All the experimental data have been tested by the method proposed by herington and 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 good agreements with the experimental data.更多还原
