测定了苯—甲醇— 1_1型电解质 (LiCl、NaBr、KI)、四氯化碳—甲醇— 1_1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。
The effects of LiCl, NaBr and KI, LiCl, NaBr and KI on the stability of the system were investigated under constant pressure (1 101 kPa) Vapor-liquid equilibrium salt effect parameters. The theoretical calculation is based on Pierotti’s calibrated particle theory. The hard-sphere action term is calculated using the Masterton-Lee equation. The soft action action term uses the simplified radial distribution function suggested by Hu et al. The intermolecular force is at the Lennard-Jones potential energy function Based on the calculation, the contribution of dipole-dipole, dipole-induced dipole, charge-dipole between ions and polar molecule and charge-induced dipole between molecule and molecule are calculated. According to the properties of solvent And the solution structure to make some reasonable assumptions. On this basis, the theoretical calculation and experimental results are basically consistent.
