| titleOfInvention | Process for producing aromatic dicarboxylic acid |
| abstract | The method for manufacturing aromatic dicarboxylic acid according to the formula 1 contains the first step of bringing a nitroaryl nitrile to react with a fluorenylidenebisphenol compound in the presence of an alkaline compound to obtain a corresponding di(cyanoaryloxy) derivative; and the second step of hydrolyzing the di(cyanoaryloxy) derivative to convert into a corresponding dicarboxylic acid,n nwhere, R1 to R6 are each independently a hydrogen, an alkyl group, or an aryl group, and they may be the same with or different from each other. n Since the method does not use halide, the load to purification of the product is significantly light, and the aromatic carboxylic acid which is useful as a monomer for manufacturing polymers is readily obtained at a high purity. |
