摘要
Disclosed is an environmentally benign and simplified method for preparing aromatic dicarboxylic acid. In the disclosed method, a mixed solvent composed of aromatic mono-carboxylic acid and water, instead of conventionally used low molecular weight carboxylic acid such as acetic acid, is used as a reaction solvent for an oxidation process; manganese and a small amount of transition metal element are used as catalysts; and carbon dioxide is used as a reaction stabilizer. Accordingly, it is possible to improve the yield and selectivity of the aromatic dicarboxylic acid.
