无水AlCl_3催化合成对甲基-N,N-二氰乙基苯胺

Synthesis of p-Methyl-N,N-bis(2-cyanoethyl) aniline Catalyzed by AlCl_3

对甲基苯胺与丙烯腈在AlCl3催化下发生加成反应合成对甲基-N，N-二氰乙基苯胺。最佳反应条件为：对甲基苯胺934mmol，n（对甲基苯胺）：n（丙烯腈）=1．0：2．8，w（AlCl3）=30％（以对甲苯胺质量计），于78℃～90℃反应8h，收率93％。

p-Methyl-N,N-dicyanoethyl-aniline in yield of 93% was synthesized from p-methyl-aniline and acrylonitrile in the presence of AlCl3. The optimal reaction conditions at 78℃ - 90℃ for 8 h were as follows： p-methyl-aniline was 934 mmol, n（p-methyl-aniline） ： n（acrylonitrile） = 1.0：2.8, w （ AlCl3 ） = 30% （ calcd for mass of p-methyl-aniline）.
