摘　　要：论述了三丙酮胺纯度对加氢和还原胺化反应的影响。使用纯度较高的三丙酮胺有利于加氢和还原胺化反应的进行及产品的分离。确定了以丙酮为溶剂的重结晶方法提纯三丙酮胺，可使三丙酮胺质量分数达到９８．６％。结晶母液可以不经分离。The effects of triacetoneamine concentration on hydrogenation and amination were discussed.It was ascertained that triacetoneamine with higher purity would give good results on hydrogenation,amination and seperation of the product.Triacetoneamine recrystallization method using acetone as solvent was established.Thus,the content of triacetoneamine could reach to 986%.The mother liquor could be used for the preparation of triacetoneamine.
