| 摘 要： | 木文采用CPⅡ型沸点仪测定了在93.33kPa下甲醇-乙醇-水-盐(NaCl,NaBr,Nal,LiCl,CaCl_2)体系的气液平衡数据。实验证明,当三元混合溶剂的相对组成固定时,体系的沸点与加入的盐量呈线性关系,用热力学理论导出了该线性方程,用Gibbs相律探讨了该线性关系的起因。

| Abstract: | The vapor-liquid equilibrium data of methanol-ethanol-water-NaCl, NaBr, Nal, LiCl and CaCl2 were measured with the CP I ebulliometer at 93. 33 kPa. We find a linear relationship between the boiling temperature and the mole fraction of the salt added when the relative composition of the ternary solvent is fixed. Also, a linear equation for the equilibrium was derived by using the thermodynamical theory and the origination of the linear relationship was discussed with Gibbs phase rule. |
