根据精馏分析原理可知用精馏的方法不能获得含水量低于7%的有机溶剂,用溶液的热力学处理盐影响恒沸物气液平衡的数据,证实了加入无水氯化钙使有机溶剂脱水是有效的.文章讨论了无水氯化钙脱水的机理,并提出了有机溶剂脱水的合适工艺.
According to the principle of distillation analysis, the organic solvent with less than 7% water content can not be obtained by the method of rectification. The data of thermodynamic treatment of salt affected the gas-liquid equilibrium of azeotrope with the solution confirmed that adding anhydrous calcium chloride to make the organic solvent Dehydration is effective.This paper discusses the mechanism of dehydration of anhydrous calcium chloride and proposes a suitable process for the dehydration of organic solvents.
