| titleOfInvention | A kind of N- cyanoethyl aniline zero-discharge production process |
| abstract | The invention discloses a kind of production technologies of N- cyanoethyl aniline zero-emission, this technique uses aniline, acrylonitrile for raw material, catalyst is added, hydroquinone synthesizes N- cyanoethyl aniline in water phase, normal pressure recycles excessive acrylonitrile after reaction, recycling finishes slow cooling to 25 °C hereinafter, filtering and product being washed with a small amount.Mother liquid coming and washing water are used as next secondary response bottom water after collecting, catalyst and hydroquinone are added according to the residual quantity of the catalyst of mixing bottom water and hydroquinone when next secondary response feeds intake, catalyst total amount is equal with first time inventory, the N- cyanoethyl aniline content San 98% being obtained by filtration, the bis- cyanoethyl aniline content San 1.5% of N, N-.The three-waste free discharge in production procedure, is truly realized technique of zero discharge. |
