Method for producing trimellitic anhydride |
| abstract |
(57) [Summary] (Modified) [Objective] To provide a method for producing trimellitic anhydride by liquid phase oxidation of pseudocumene in the presence of a heavy metal-based oxidation catalyst and a bromine source. Composition: Pseudocumene is oxidized in the presence of cerium, cobalt, manganese and optionally zirconium, bromine catalysts, all cerium is added in the second stage of oxidation, and most bromine is also added in the second oxidation stage. Added. |
