以Chüeh和Ziegler所得的物料衡算公式为基础,导出一个新的与色谱实验数据直接关联的计算活度系数的公式,提出相应的实验规程。以此对正已烷—邻苯二甲酸二壬酯;正庚烷-邻苯二甲酸二壬酰及苯-1、2、3、4-四(氰乙氧基甲基)甲烷三个体系的挥发组分有限浓度时的活度系数作了测定,温度效应明显,其中n-C_6~0—DNP在40℃时的计算结果与溶解度法测定的文献数据对照,结果令人满意。

The GLC menthod for determination of the activity coefficients of the volatile components in binary systems has been studied. Based on Chueh Ziegler method, a regular experimental process and a new formula for calculating activity coefficients from GLC data are presented. Three systems: n-hexane - Dinonyl phthalate (DNP), at 40,60 and 80℃ n-heptane - DNP at 60 and 80℃, benzene (φH) - tetracyanotethylated pentaerythritol (TCP) at 50,65 and 80℃, were investigated by GLC method, and good results were obtained. For temperature effect, the GLC method seems more sensitive than the classical one.
