| titleOfInvention | A kind of catalytic synthesis method of p-aminobenzonitrile |
| abstract | The invention discloses a method for synthesizing p-aminobenzonitrile. The method comprises the following steps: mixing a nitrobenzene substitute with ammonia gas and a second gas, and reacting in a fluidized bed reactor in the presence of a catalyst to obtain p-aminobenzonitrile. Aminobenzonitrile, the second gas is air, oxygen or inert gas. The nitrobenzene substituted product is p-nitrobenzoic acid or p-nitrotoluene, and p-aminobenzonitrile is obtained by reacting under the ammonia oxidation catalytic system. The synthesis method provided by the invention has simple process, low production cost and high production efficiency, can realize continuous production of p-aminobenzonitrile, reduce the amount of three wastes, and can be applied to industrial production. |
