N,N-二乙基乙二胺的制备

Preparation of N,N-diethylethanediamine

以二乙胺、丙烯酰胺为原料，通过加成与霍夫曼重排反应合成二乙基乙二胺。重点讨论了反应温度、反应时间以及浓度对产品收率的影响。

Diethylamine and acrylamide are used as raw materials, N,N-diethylethanediamine is synthesized by the addition of them through the Hofmann reaction. Influence of the reaction temperation, reaction time and concentration on the yield of product were discussed in detail. A good technological parameter has been obtained.
