| 摘 要： | 用气液色谱仪与改进的斜式沸点计系统地测定了64组二元系的溶质无限稀释活度系数。其中文献已有报道的体系,测定结果与报道的数据符合良好。对10个二元系测定了几个温度下的数值,进行了分析讨论,并回归出9个不对称二元系的无限稀释活度系数与温度的线性关系式。计算了无限稀释条件下偏摩尔焓变量。

| Abstract: | The activity coefficients of 64 binaries and the relations of 10 activity coefficients with temperature were measured by gas chromatography and modified inclined ebulliometer. The regressed linear equations for activity coefficient-temperature dependence of nine two-component systems at infinite dilution were obtained. The corresponding partial molar enthalpies Were calculated. |
