| titleOfInvention | Multi-element oxide catalyst for preparing fluorenone by oxidation of fluorene, preparation method and application |
| abstract | The invention provides a multi-component oxide catalyst for preparing fluorenone by oxidizing fluorene, a preparation method and application thereof. The precursor materials of Co, Cu and X are mixed by physical mechanical grinding, wherein X=K, Na, Mg, Ca, Then calcined at a high temperature to obtain a multi-component oxide catalyst. The catalyst is used to catalyze the oxidation of fluorene to prepare fluorenone, and the steps are as follows: add fluorene to a solvent, then add a catalyst, and pass oxygen to react under the reaction condition of 40-80°C. The catalyst only uses mechanical grinding to mix the precursor raw materials, and then directly roasts the catalyst at high temperature to obtain the catalyst. It does not need water or other organic solvents to mix the precursor raw materials, avoiding complex processes such as waste water and a large amount of solvent recycling, and is easy to operate and low in cost. , and the separation between the heterogeneous oxide catalyst and the product is convenient in the later stage, and the regeneration treatment of the catalyst after the reaction is simple. |
