Zusammenfassung:A method for oxidizing a dimethyl aromatic compound includes reacting the dimethyl aromatic compound and an oxidant in the presence of a catalyst and a co-catalyst in a solvent to produce a reaction product comprising an aromatic dicarboxylic acid. The catalyst comprises cobalt, manganese, and bromine. A weight ratio of cobalt to manganese is equal to or greater than 1:1. The co-catalyst comprises at least one of cerium or iron. The co-catalyst is present in an amount in a range of 10 ppm to 200 ppm, based on a total weight of the dimethyl aromatic compound and the solvent. The aromatic dicarboxylic acid is present in the reaction product in an amount equal to or greater than 70 wt.%, or equal to or greater than 90 wt.%, based on a total weight of solids in the reaction product.
