| titleOfInvention | Catalyst for synthesizing partial anhydride |
| abstract | The invention relates to a catalyst for synthesizing meta-anhydride, which mainly solves the problem that the reaction for preparing the meta-anhydride by oxidizing meta-trimethylbenzene in the prior art generates a plurality of byproducts, so that the yield of the meta-anhydride is low. The invention adopts the technical scheme that the vanadium oxide supported catalyst comprises the active component of at least one of vanadium element, titanium element, alkaline earth metal element and III B group element, thereby better solving the technical problem, improving the selectivity of the catalyst to the meta-anhydride, reducing the generation of byproducts and effectively improving the yield of the meta-anhydride. |
