二乙基烯丙基胺的合成

Synthesis of Diethyl Allylnime

以烯丙基氯作烷基化试剂 ,在常压、不加催化剂的情况下合成了二乙基烯丙基胺 ,并对原料配比、水浴温度、加料方式与时间、以及沸腾反应时间对产率的影响进行了研究 .结果表明 ,在烯丙基氯与二乙胺摩尔比为 1.1∶1、总加料时间 2h及沸腾反应 1h时 ,二乙基烯丙基胺的产率可达 78% .

Diethyl allylamine (DEEA) was synthesized by using allyl chloride (AC) as alkylation reagent at normal pressure without catalysis. We investigated the effects of the material proportion, the feeding method and the boiling time upon the yield of diethyl allylamine. The results show that the yield can reach 78% under the following optimal conditions:the molecular ratio of allyl choride:diethyl amine= 1.1∶1, the feeding time= 2 h, and the boiling time=1 h.
