| titleOfInvention | A kind of 9-Fluorenone clean manufacturing one-step method |
| abstract | A kind of 9-Fluorenone clean manufacturing one-step method, the invention belongs to technical field of chemical synthesis, the preparation process for solving 9-Fluorenone in the prior art is complicated, at high cost, the low problem of yield, using fluorenes as raw material, benzene class reagent is solvent, and alkali is catalyst, and quaternary ammonium salt is phase transfer catalyst, under oxygen atmosphere, it is reacted under conditions of 55-60 DEG C of temperature, after the completion of reaction, adds sustained release agent, make system layering, by 9-Fluorenone oil phase layer crystallisation by cooling, 9-Fluorenone product is obtained after suction filtration, the present invention is not necessarily to washing process, 9-Fluorenone content obtained is high, reaches 99.7%. |
