报道了AlCl3和AlCl3-ZnCl2组成的催化体系对邻、间、对甲基苯胺三种异构体与丙烯腈发生加成反应合成相应的N,N-二氰乙基甲基苯胺. 其结果表明: AlCl3对该类反应具有很高的催化效率, AlCl3-ZnCl2组成的催化体系比AlCl3的催化效率更高, 其中间位、对位产物收率达92%～94%.

关键词: AlCl3, ZnCl2, N,N-二氰乙基甲基苯胺

In this paper, methyl-N,N-bis(2-cyanoethyl)aniline was synthesized by the reaction of o-methylaniline, m-methylaniline or p-methylaniline with acrylonitrile in the present of AlCl3 or AlCl3-ZnCl2. The experimental results proved that AlCl3 was an excellent catalyst, and AlCl3-ZnCl2 was better than AlCl3 in catalyzing this reaction, and the yields of m- and p-products were 92%～94%.

Key words: methyl-N,N-bis(2-cyanoethyl)aniline, ZnCl2, AlCl3
