| titleOfInvention | A kind of preparation method for the catalyst that caprolactam is prepared for cyclohexanone one-step method |
| abstract | The invention provides a kind of preparation method for the catalyst that caprolactam is prepared for cyclohexanone one-step method, comprise the following steps, metal hydroxides is slowly added into certain density acid solution；After certain time, the mixed solution of the first metal salt and second of metal salt is slowly added to；Certain density organic formwork agent is added dropwise；A period of time is aged at room temperature；Load autoclave under certain temperature react, then be down to after room temperature washed, dry, be calcined, obtain catalyst；Wherein the first metal salt is the acetate or nitrate corresponding to a kind of metal in first and second main group；Second of metal salt is the acetate or nitrate corresponding to a kind of metal in transition metal；Metal hydroxides be the periodic table of elements third and fourth, the hydroxide corresponding to a kind of metal in five main groups.The catalyst of the present invention, greatly shortens the technological process that caprolactam is synthesized, equipment investment is substantially reduced, and is the revolutionary breakthrough of Caprolactam Industry. |
