| titleOfInvention | A kind of preparation method and application of pyromellitic acid |
| abstract | The present application discloses a preparation method and application of pyromellitic acid. The method includes at least the following steps: Step 1. React a mixture containing compound I, compound II and aliphatic alcohol to obtain a six-membered cyclic carboxylic acid ester; compound I has a conjugated C=C bond and a -COOH group; compound II has a C=C and -COOH group; step 2, the six-membered cyclic carboxylic acid ester is subjected to dehydroaromatization reaction and hydrolysis reaction, The pyromellitic acid is obtained. The present application uses trans, trans-muconic acid and fumaric acid as raw materials, and trans, trans-muconic acid and fumaric acid can all be derived from biomass resources, which can reduce the dependence of pyromellitic acid synthesis on petroleum resources, and provides A green synthetic route of pyromellitic acid. And the method of the present application can obtain pyromellitic acid with high selectivity. |
