| titleOfInvention | Method for stabilizing catalytic system and synthesizing adiponitrile |
| abstract | The invention provides a method for stabilizing a catalytic system and synthesizing adiponitrile, which comprises the following steps: and adding heteropoly acid into the reaction liquid to carry out hydrocyanation reaction to prepare adiponitrile. The invention provides a method for effectively stabilizing a secondary hydrocyanation reaction catalytic system, which greatly improves the cycle times of a catalyst and reduces the consumption of the catalyst, thereby greatly reducing the cost of the secondary hydrocyanation reaction, further reducing the production cost of adiponitrile, and having very important economic significance for the industrial production of the adiponitrile. |
