摘要： 用双循环武加压汽液平衡装置测定了苯-正庚烷-乙醇三元体系在101.3、302.5、506.8、709.3、810.6kPa下的汽液平衡数据。根据有关二元体系在对应压力下的汽液平衡数据所求得的能量配偶参数,对该体系的汽液平衡进行了预测,计算值与实验值符合良好。

Abstract: The vapor liquid equilibrium (VLE) data of benzene-n-heptane-ethanol ternary system under pressure of 101. 3, 302. 5, 506. 8, 709. 3, 810. 6 kPa were determined with the double circulating VLEdevice under pressure. The ternary VLEdata were predicted with multicomponent Wilson equation, and the energy paired parameters were obtained from the correlation of VLEfor three binary systems i. e. benzene-n-heptane, benzene-ethanol, n-heptane-ethanol under corresponding pressure. The good agreements between predicted values and experimental data were obtained.

Key words: Vapor liquid equilibrium under pressure, Benzene-n-heptane-ethanol system, Energy paired parameters
