| titleOfInvention | Method for preparing phthalide by catalytic liquid phase selective oxidation |
| abstract | The application discloses a method for preparing phthalide by catalytic liquid phase selective oxidation. The method comprises the steps of contacting a raw material containing o-xylene with a catalyst in the presence of an oxygen source, and reacting to obtain phthalide; wherein, air or oxygen is used as an oxygen source, and nitrogen-doped carbon-supported bimetal is used as a catalyst. The method has the advantages of mild reaction conditions, high raw material conversion rate and product selectivity, recyclable catalyst and the like. |
