| titleOfInvention | Catalyst for preparing partial anhydride |
| abstract | The invention relates to a catalyst for preparing meta-anhydride, which mainly solves the problems of poor catalyst performance and low yield of the meta-anhydride in the prior art because a plurality of byproducts are generated in the oxidation reaction of the meta-tritoluene. The invention adopts the technical scheme that the vanadium oxide catalyst comprises the active component of vanadium element, titanium element and at least one of alkali metal element and nonmetal element, thereby better solving the technical problem. |
