【摘要】 在９９．９９２ｋＰａ压力下用Ｅｌｉｓ汽液平衡釜测定了丁酮＋乙苯、丁酮＋ｏ－二甲苯、丁酮＋ｍ－二甲苯、丁酮＋ｐ－二甲苯４个二元体系的汽液平衡数据，并进行了恒压下热力学一致性的检验．用Ｗｉｌｓｏｎ方程关联了实验数据，拟合精度令人满意更多还原

【Abstract】 Vapor liquid equilibrium data were determined in an Ellis still at 99 992 kPa for 2 butanone+ethyl benzene, 2 butanone+ o xylene, 2 butanone+ m xylene and 2 butanone+ p xylene,respectively A thermodynamic model proposed by Hayden O’connell 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 the demand of thermodynamic consistency Wilson equation was selected to correct composition and component’s activity coefficient of the liquid phase The calculated values of the vapor composition are in good agreement with experimental data更多还原
