| titleOfInvention | A kind of method being prepared 9-Fluorenone by Industrial fluorene |
| abstract | Being prepared a method for 9-Fluorenone by Industrial fluorene, with Industrial fluorene (purity is greater than 95%) for raw material, take alkali as catalyzer, with toluene and water for solvent, take quaternary ammonium salt as consisting of phase-transferring agent, in lower temperature with under stirring, fluorenes and oxygen-containing gas react, and fluorenes is converted into 9-Fluorenone.Select suitable reaction conditions, the transformation efficiency of fluorenes can reach 100%.The alkali that the present invention reclaims and solvent do not need the treating processes of Special complex, can recycle, be of value to industrialization, in the present invention, the technology such as recycle and reuse, recrystallization of catalyzer alkali, consisting of phase-transferring agent quaternary ammonium salt, solvent and alkali is studied, obtain pure Fluorenone, propose the technique that a more complete fluorenes prepares 9-Fluorenone. |
