| Abstract: | A green technology of N-cyanoethylaniline was reported,which involved the addition of acrylonitrile with aniline.The distinct modification was focused on the chemical process modification,such as using hydrochloric acid and zinc chloride as combined catalysts,with several benefits: high purity(95.8 %),high yield(>98 %),350 kg waster water(<1000 mg/L in COD) per ton of N-cyanoethylaniline.Compared with the traditional process,yield improvement in 2 %~3 %,COD emissions decreased more than 80 %. |
