1,2-二氯乙烷冷冻干燥工艺的研究

Research on the Lyophilization Technology of 1,2-Methylene Dichloride

1,2-二氯乙烷是一种常用的有机溶剂,在很多工业生产中作为溶剂时可重复使用,但在一些要求无水条件下进行反应的生产中,需对其回收后进行干燥,达到要求后方可使用。文章对二氯乙烷回收采用的冷冻干燥工艺进行研究。

1,2 - methylene dichloride is a kind of common organic solvent and can be recycled in industrial production. But some reactions need it without any water. So it can be used only after it is reclaimed and dried. To recycle it, the lyophilization technology of 1,2 - methylene dichloride is researched in the article.
