【摘要】 测定了苯—甲醇— 1₁型电解质 （LiCl、NaBr、KI）、四氯化碳—甲醇— 1₁型电解质 （LiCl、NaBr、KI）两个体系在恒压 （ 1 0 1 .3kPa）条件下的汽液平衡盐效应参数。理论计算以Pierotti的定标粒子理论为基础 ,硬球作用项采用Masterton -Lee方程计算 ,软球作用项采用胡英等人建议的简化的径向分布函数 ,分子间力在Lennard -Jones位能函数基础上计入极性分子间偶极—偶极、偶极—诱导偶极 ,离子与极性分子间的电荷—偶极以及离子与分子间的电荷—诱导偶极的贡献 ,并根据溶剂性质和溶液结构作出一些合理的假设。在此基础上 ,理论计算与实验结果基本相符。更多还原

【Abstract】 Salt effect parameters of polar (mathanol)-nonpolar (benzene or carbon tetrachloride)binary solution with 1-1 type electrolytics (LiCl, NaBr, KI) were determined by isobaric VLE experiments. The calculation of them was based on Pierotti’s scaled particle theory about salt effect. The term of hard sphere interactions was calculated by Masterton-Lee’s equation, and that of soft sphere interactions was treated by Y. Hu’s radial distribution function. The interactions of dipole-dipole, dipole-induced dipole between polar molecules, charge-dipole between ions and polar molecules, charge-induced dipole between ions and molecules were taken into account in the energy function besides the Lennard-Jones energy, and rational assumptions were adopted according to the properties of polar-nonpolar binary solution. The results of calculation were in agreement with the experimented results.更多还原
