| titleOfInvention | A kind of method for directly preparing cyclohexanone from benzene |
| abstract | The present invention is a method for directly preparing cyclohexanone from benzene. The method comprises the following steps: placing benzene, hydroxylamine salt, a first catalyst, a second catalyst, Bronsted acid and water in an autoclave, and passing N to carry out Replace, then heat up to 60～150℃, react for 0.5～3h; then pass hydrogen to 1～5MPa and react for 1～6h, cool down to room temperature, centrifuge to separate the catalyst and reaction solution, the reaction solution is obtained after neutralization extraction and separation The product cyclohexanone. The method overcomes the disadvantages of many reaction steps, complicated product separation process, and high energy consumption in the traditional cyclohexanone synthesis process, and has the advantages of simple and easy-to-obtain raw materials, simple synthesis process, mild reaction conditions, and simple product separation, etc. One-time feeding can produce cyclohexanone by one-pot method of benzene, and the yield of cyclohexanone can reach 12%. |
