DMF如何做无水处理? 以下是引用 licaimei 在2006-8-16 14:32:00的发言: 先加入CaH2 室温搅拌过夜,第二天减压蒸出即可,简单易操作! 我在上面的回帖中的一段话,不知你看到没有:The decomposition is catalysed by acidic or basic materials, so that even at room temperature DMF is appreciably decomposed if allowed to stand for several hours with solid KOH, NaOH or CaH2. If these reagents are used as dehydrating agents, therefore, they should not be refluxed with the DMF. 用氢钙是非正常操作,请不要误导大家! 查看更多
