Production method of aromatic polycarboxylic acids |
| abstract |
The present invention relates to a process for preparing aromatic polycarboxylic acids, and more particularly, to a solvent containing aliphatic carbonic acid having 1 to 6 carbon atoms in the presence of cobalt-manganese-bromine and, if necessary, a catalyst to which a transition metal or a lanthanide metal is added. In the preparation of the aromatic polycarboxylic acid by oxidizing the polyalkylaromatic compound or its oxidized intermediate with an oxygen-containing gas, by adding carbon dioxide to the oxygen-containing reactor, the reaction activity is enhanced and the side reactions are reduced. It relates to a method for producing an aromatic polycarboxylic acid. |
