摘要
以四氢呋喃、乙二醇二甲醚、异丙醇和乙醇等为例,总结了有机溶剂中水分的脱除方法,将有机溶剂中脱水的常用方法主要分为:①干燥剂脱水法;②渗透气化的膜分离方法;③特殊精馏法:包括萃取精馏、共沸精馏法等。并对这些方法作了分析与讨论。
The methods of dehydration from organic solvents such as tetrahydrofuran. 1, 2- dimethoxythane, isopropanol alcohol and so on were reviewed. The methods were divided into three main classes： （1）desiccant dehydration; （2） pervaporation membrane method; （3）special distillation： including azeotropic distillation and extraction distillation etc. Finally, the analysis and discussion for these methods were made.
