摘　　要：本文介绍了以N-氰乙基-N-羟乙基苯胺、丙烯腈为原料,以四丁基溴化铵为催化剂,在碱性条件下进行氰乙基化反应,制备得到N-氰乙基-N-氰乙基氧乙基苯胺。重点考察了物料配比、催化剂用量、反应温度等因素对反应的影响,在最优工艺条件下,产品纯度可达96%以上。N-cyanoethyl-N-cyanoethoxyethylaniline was prepared by cyanoethylation reaction under alkaline conditions with N-cyanoethyl-N-hydroxyethylaniline and acrylonitrile as materials, tetrabutylammonium bromide as catalyst. The effects of material ratio, reaction temperature and catalyst dosage on the reaction were studied. Under optimum conditions, the purity of the product could reach above 96%.
