| 摘 要： | 文章考察了乙醇加入量、温度等因素对氯化钾和氯化钠单独存在及二者共存时在水溶液中的溶解度的影响,研究结果表明:在不同温度下加入乙醇可使氯化钾和氯化钠在水中的溶解度均降低,但其降低的幅度不同;两种盐类在水中溶解度的差异将随温度的升高而减小。在此基础上,文章提出了利用溶剂分离氯化钾和氯化钠的新工艺初步方案。

| Abstract: | In this paper,the effects of temperature and ethand concentration on the saturated solubility of potassium chloride or sodium chloride and both are studied. The results show that the saturated solubility of KCl and NaCl would decrease as concentration of ethand increases, and the solubility of KCl desends more obviously. For the mixed salt solution, the difference in the saturated solubility of KCl and NaCl would disapear as the temperature arises. The action mechanism of ethand on the saturated solubility of salt is briefly explored. And finally, one process for separation of KCl from NaCl is proposed. |
