【Abstract】 Vapor-liquid equilibrium data were determined in a CP-I still at 99 992 kPa for t-butanol+1,2,4-trimethyl benzene,t-butanol+1,3,5-trimethyl benzene and t-butanol+1,2,3-trimethyl benzene, respectively. A thermodynamic model proposed by Hayden-O’connell for accounting the nonideal behavior of the vapor 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 the demand of thermodynamic consistency Wilson equation was selected to correct the composition and the activity coefficient of the components in liquid phase The calculated values of the vapor composition are in good agreement with experiment data.更多还原
