| titleOfInvention | Method for co-producing cyclohexylamine and dicyclohexylamine and catalyst system used in method |
| abstract | The invention discloses a method for coproducing cyclohexylamine and dicyclohexylamine and a catalyst system used for the method. The method comprises the following steps: (1) aniline, cyclohexanone, ammonia and hydrogen serving as raw materials pass through a first-stage reactor filled with a loaded Rh-Ni catalyst to obtain first reaction liquid; (2) and (3) allowing the first reaction solution to pass through a second-stage reactor filled with a loaded Rh-Co catalyst to obtain a reaction solution containing cyclohexylamine and dicyclohexylamine. The method has the advantages of cheap and easily-obtained raw materials, high conversion rate, good product selectivity, long catalyst service life, simple process, high automation degree, low labor intensity and low production cost by adopting a continuous process, can co-produce dicyclohexylamine with high added value, can adjust the composition of the product by changing reaction conditions according to the market demand condition of the product, and is suitable for industrial large-scale production. |
