无水AlCl_3催化合成N,N-二氰乙基间氯苯胺的研究

Synthesis of m-Chloide-N,N-bis(2-cyanoethyl)aniline Catalyzed by AlCl_3

报道了间氯苯胺与丙烯腈在无水AlCl3的催化下发生加成反应合成N，N-二氰乙基间氯苯胺，其合适的反应条件是：AlCl3的用量为间氯苯胺的60％（物质的量比），反应温度为75～90℃，反应时间20h。其结果表明：AlCl3对该反应具有很高的催化效率，产物收率可达86％。

In this paper, a new process for synthesizing m - chloro - N,N - bis（2 - cyanoethyl） aniline from m - chioroaniline and acrylonitrile was reported by using AlCl3 as the catalyst. The experimental result had proved that AlCl3 was an excellent catalyst, The reaction was carried at 75 - 90 ℃ for 20 h, the amount of the catalyst AlCl3 used was 60 % of the weight of m - chloroaniline, the conversion obtained was about 85 % with a yield over 95 %. In comparison with other methods, there were some advantages in this method： the reaction temperature was low, the reaction time was not long, the yield was high and the product could be easily separated and purified. It could be therefore mass - produced which was in favor of its application to the synthesis of dyes.
