一般描述

二氯甲烷(DCM)是一种氯化有机溶剂,在工业和有机合成中广泛应用。它沸点低,密度高,与水不混溶。DCM易于随时间降解,添加异戊烯作为稳定剂可进行抑制。

应用

二氯甲烷
  • 有机合成
a) Dakin, Dess-Martin and Ley Oxidation(氧化)
b) 烯炔复分解, 广泛使用二代格拉布斯钌配合物催化剂
c) Jacobsen-Katsuki环氧化
d) 固定化Boc-NH2-聚乙二醇-血浆层的Boc脱保护
e) 与膦或胺反应形成相应的烷基化产物
  • 胶粘剂和油漆制剂
  • 萃取浓度分析
  • 快速柱色谱
  • 电子行业印刷电路板
  • 三醋酸纤维素生产
