| titleOfInvention | Catalyst for producing aromatic polycarboxylic acid by liquid phase oxidation |
| abstract | The invention relates to a catalyst for producing aromatic polycarboxylic acid by liquid-phase oxidation, which mainly solves the problem that the bromine consumption in the catalyst is too high when the aromatic polycarboxylic acid is prepared by liquid-phase oxidation of polyalkyl-substituted aromatic hydrocarbon in the prior art. The catalyst for producing the aromatic polycarboxylic acid by adopting liquid-phase oxidation comprises Co salt, Mn salt, lanthanide salt, a bromine-containing compound and anthraquinone disulfonic acid, wherein the technical scheme comprises the following steps of (200-300) parts by weight of Co salt, Mn salt, lanthanide salt, Br and anthraquinone disulfonic acid, wherein the number of the Br parts by weight of the lanthanide salt and the anthraquinone disulfonic acid is 500, (20-100) parts by weight of (1000-2000) parts by weight of (5-20), the technical problem is better solved, and the catalyst can be used for producing the aromatic polycarboxylic acid by liquid-phase oxidation of polyalkyl-substituted aromatic hydrocarbon. |
