用气液色谱法测定三元系中挥发组分有限浓度时活度系数的研究

Study on Gas-Liquid Chromatographic Method for Determination of Activity Coefficients of Volatile Components in Ternary Systems

本文研究了用色谱方法测定三元系中二个挥发组分在有限浓度时的活度系数,提出了实验规程及导出了用色谱数据计算活度系数的公式。测定了(1)苯-环己烷-邻苯二甲酸二壬酯(DNP)在40℃、60℃时,(2)苯-环己烷-角鲨烷(SQ)在60℃、80℃时二个体系中挥发组分(苯及环己烷)的活度系数。

In this paper, the gas-liquid chromatographic method for determination of activity coefficients of two volatile components in ternary systems was studied. A formula for calculating activity coefficients from gas-liquid chromatographic data was presented. Two systems. (1) Benzene -- Cyelohexane--Dinonyl-phthalate (DNP) at 40℃ and 60℃, (2) Benzene-Cyclohexane-Squalane (SQ) at 60℃ and 80℃ were investigated.
