| titleOfInvention | A kind of preparation method of efficient power-saving environmental protection N- ethyl ns-cyanoethyl aniline |
| abstract | The present invention is the preparation method of efficient power-saving environmental protection N ethyl n cyanoethyl anilines, be pressed into including in, neutralization reaction, rectifying addition reaction and distillation, in be pressed into, during ethyl alcohol, aniline and the first catalyst are put into pressure reaction kettle, the first catalyst is by phosphorus oxychloride and copper chromium by weight 5：12 mix, and obtain rectifying after N ethyl aniline crude products after reaction；In addition reaction, by N ethyl aniline and acrylonitrile and the second catalyst input addition reaction kettle, the second catalyst is by zinc chloride and copper chromium by weight 6：2 mix, and reaction terminates to distill after N ethyl n cyanoethyl aniline crude products.The present invention can further improve the reaction selectivity of N ethyl n cyanoethyl anilines；Separately improve the selectivity of N ethyl n cyanoethyl anilines again while reducing using energy source and shortening the reaction time. |
