| titleOfInvention | A kind of method for preparing lactone by catalytic oxidation of cycloalkanol/cycloalkanone |
| abstract | The invention provides a method for preparing lactone by catalytic oxidation of cycloalkanol/cycloalkanone, belonging to the technical field of fine chemicals. In the method, molecular oxygen is used as oxygen source, vanadium nitride/carbon material is used as catalyst, and cycloalkanol/cycloalkanone is selectively oxidized into lactones such as γ-butyrolactone and δ-valerolactone in a liquid-phase solvent , specifically: at room temperature, put the catalyst, cycloalkanol/cycloalkanone and solvent into the autoclave, then feed the oxygen source, seal the reactor, stir and heat up to 40-180 ℃, the reaction time is 0-12h Then, if there is oxygen consumption during the reaction, supplement it; finally, it is cooled to room temperature and decompressed to normal pressure. The present invention provides a brand new lactone preparation route; compared with the traditional high-temperature gas-phase oxidation method or peroxide oxidation method, the present invention adopts a liquid-phase catalytic oxidation method, uses molecular oxygen as an oxidant, and does not use peroxide, The reaction conditions are mild, safe and environmentally friendly, and have significant innovation and important application prospects. |
