摘　　要：用CP I型汽液平衡双循环釜测定了叔丁醇 +偏三甲苯、叔丁醇 +均三甲苯、叔丁醇 +连三甲苯 3个二元体系在压力为 99 992kPa时的等压汽液平衡数据,并进行了热力学一致性检验.用Wilson方程关联了实验数据,拟合精度令人满意.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.
