为研究汽液平衡盐效应的规律，广泛积累这方面的实验数据是非常必要的，在１０１．３ｋＰａ压力下用改进的Ｏｔｈｍｅｒ平衡仪分别测定了溶有不同浓度氯化锂、氯化钙的四氯化碳—正丙醇体系的汽液平衡数据．用Ｆｕｒｔｅｒ拟二元体系模型处理溶盐三元体系．以Ｈｅｒｉｎｇｔｏｎ方法对实验体系作了热力学一致性校验，并以ｖａｎＬａａｒ方程及Ｗｉｌｓｏｎ方程关联了实验数据，得到了较好的结果．
In order to study the law of vapor-liquid equilibrium salt effect, it is necessary to widely accumulate the experimental data in this respect. Under the pressure of 101.3kPa, the modified Othmer balancer was used to measure the solubility of lithium chloride and calcium chloride Vapor-liquid equilibrium data for carbon-carbon monoxide-n-propanol system. Treating the salt - soluble ternary system with Furter quasi - binary system model. The Herington method was used to verify the thermodynamic consistency of the experimental system. The experimental data were correlated with van L aar equation and Wilson equation, and good results were obtained.
