| titleOfInvention | Preparation method of 9, 9-dimethylacridine |
| abstract | The invention belongs to the technical field of organic synthesis, and particularly relates to a preparation method of 9, 9-dimethylacridine. The preparation method comprises the following steps: mixing 2- (2- (phenylamino) phenyl) propane-2-alcohol and a hydrogen type molecular sieve catalyst in an organic solvent, reacting for 2-4 h at 20-50 ℃, carrying out solid-liquid separation to obtain a liquid phase, and removing the organic solvent in the liquid phase to obtain the catalyst. The method has the advantages of mild reaction conditions, simple and convenient operation, environmental protection, high product yield and recyclable catalyst, and is suitable for large-scale industrial production. |
