摘　　要：应用电导率仪在288-308K温度范围内测定了LiCl在纯有机溶剂（异丙醇）中的电导率；利用公式计算了LiCl的摩尔电导率；按Kohlrausch经验公式，使用Origin软件进行线性拟合，作图外推求得LiCl在异丙醇中的无限稀释摩尔电导率λ0值；并讨论了LiCl在异丙醇中的电导率、摩尔电导率、活度系数和相对偏摩尔自由能随溶液浓度和温度的变化关系及其温度对LiCl溶液无限稀释摩尔电导率的影响。The electric conductivity of LiCl in 2-Propanol solvent was measured using conductivity meter at 288 - 308 K. The molar conductivity of LiCl was calculated with the help of the formula. The data were linear fitted with the software of Origin according to Kohlrausch empirical formula. And the molar conductivity at infinite dilution of LiCl was obtained by the extrapolation method. The changes of the conductivity, molar conductivity, activity coefficient and relative partial molar free energy of LiCl with concentration and temperature of the solution were discussed. Moreover, the influence of temperature on molar conductivity at infinite dilution of LiCl was also discussed.
