摘    要:本文根据氯仿、苯、正丁醇有关二元体系实测数据统一关联所得的能量参数关联式,用Wilson方程对氯仿-苯-正丁醇三元体系在101~303kPa压力下的汽液平衡作了预测,并与本工作的实测数据比较,二者符合良好。实验结果表明,这三元体系与氯仿-苯-乙醇体系的汽液相平衡行为具有相似的规律。

关 键 词:醇烃体系,加压汽液平衡,氯仿-苯-正丁醇体系

Abstract:The vapor liquid equilibrium data for chloroform-benzene-1-butanol ternary system were determined at pressure up to 303.0 kPa with the dual circulating vapor liquid equilibrium apparatus. The three-component Wilson equation with the unitedly cor-related expression of the corresponding binary systems was used to predict the equilibrium data. The predicted results are in good agreement with the experimental data. The experi-mental results indicate that this ternary system has the similar vapor-liquid equilibrium be-havior with the chloroform-benzene-ethanol system. Some chloride ions are generated in both ternary systems when the temperature is over 400 K.
Keywords:hydrocarbon-alcohol systems   VLE at superatmospheric pressure   chloro-form-benzene-1-butanol system
