| titleOfInvention | Catalyst for synthesizing pyromellitic dianhydride by oxidizing pyromellitic dianhydride |
| abstract | the invention relates to a catalyst for synthesizing pyromellitic anhydride by gas-phase oxidation of durene, mainly solve the problem that the synthesis reaction of pyromellitic anhydride produces many by-products in the prior art, resulting in low yield of pyromellitic anhydride, the invention adopts an oxide catalyst, the catalyst adopts alpha-Al 2 O 3 , silicon carbide, ceramic rings or a mixture thereof as a carrier, and the active component comprises at least one of vanadium element, non-metal element, IVA group element and IIIB group element, thereby better solving the technical problem, reducing the occurrence of side reaction during synthesis of pyromellitic anhydride, and improving the yield of pyromellitic anhydride. |
