| titleOfInvention | A method for synthesizing hexamethylenediamine from caprolactam in one step |
| abstract | The invention discloses a method for synthesizing hexamethylenediamine from caprolactam in one step. The method uses a molecular sieve loaded with copper oxide and zinc oxide as a catalyst, uses caprolactam as a raw material, and synthesizes hexamethylenediamine in one step in the presence of ammonia and hydrogen; In the catalyst, the mass ratio of copper oxide, zinc oxide and molecular sieve is 15-35: 2-10: 55-83. The catalyst is prepared by the following steps. First, the Beta molecular sieve is acid-treated to obtain a high silicon-aluminum ratio Beta molecular sieve carrier, and then Copper oxide was loaded by ammonia distillation method, and then zinc oxide was loaded by deposition precipitation method. The method for synthesizing hexamethylenediamine provided by the invention simplifies the production process of hexamethylenediamine, and the catalyst used in the reaction has simple preparation process, stable performance and good reaction performance. |
