研究了异丙醚的提纯工艺。采用酸洗的方法，用硫酸做酸化剂与异丙醇副产叠合油中的异丙醚反应，静止分离，水解，精馏得到高纯度的异丙醚。讨论了硫酸质量分数、硫酸与异丙醚的质量比、反应时间对反应的影响，所得异丙醚的质量分数大于99％。
研究瞭異丙醚的提純工藝。採用痠洗的方法，用硫痠做痠化劑與異丙醇副產疊閤油中的異丙醚反應，靜止分離，水解，精餾得到高純度的異丙醚。討論瞭硫痠質量分數、硫痠與異丙醚的質量比、反應時間對反應的影響，所得異丙醚的質量分數大于99％。

Purification process of isopropyl ether was studied.Sulfuric acid as acidifying reagent reac-ted with isopropyl ether in composite oil which was a byproduct of isopropanol,after still separation,hydroly-sis,distillation,isopropyl ether with high purity was obtained.The content of sulfuric acid,the mass ratio of sulfuric acid to isopropyl ether,the reaction time were discussed,the obtained content of diisopropyl ether was greater than 99%.
