The present invention relates to a method for producing an environmentally-friendly and simplified aromatic dicarboxylic acid, and more particularly, to a mixed solvent composed of aromatic monocarboxylic acid and water rather than a low molecular weight carboxylic acid, such as acetic acid, which is used in the prior art. By using as a reaction solvent, using a small amount of transition metal elements in addition to manganese as a catalyst, and using carbon dioxide as a reaction stabilizer, aromatic dicarboxylic acid that can improve the yield and selectivity of aromatic dicarboxylic acid while being environmentally friendly and simplified It relates to a method for producing an acid. |
