【摘要】 以苯胺为原料，先用乙醇作烷基化试剂合成Ｎ－乙基苯胺，研究了反应的影响因素，烷基化反应在２２０℃，物料配比为１∶２，反应时间３０小时，其主要产品收率可达９０％以上，纯度可达９７３％。进而再用苄氯作为苄基化试剂合成Ｎ，Ｎ－乙基苄基苯胺，并研究了反应的影响因素，苄基化反应在６０～８０℃，物料配比为１∶１，反应时间１５小时能获得最佳反应结果，主产品收率可达９０％以上，纯度可达９９％，是迄今较理想的合成路线。更多还原

【Abstract】 Abstract Effects were studied on the preparation of N-ethyl-aniline by the reactionof aniline reacted with ethanol,The reaction was run at 220℃ for 30h in a 1 to 2 mole ratio of aniline to ethanol with ayield of 90% and purity of 973%.N-ethyl -N-benzyl-aniline was synthesized from N-ethylaniline and benzyl chloride,which was carrued out under 60～80℃ for 15h in a 1∶1 mole ratio of N-ethylaniline and benzyl chloride with ayield of over 90% of N-ethyl -N-benzylaniline and purity of 99%.更多还原
