Process for producing aromatic dicarboxylic acid |
| abstract |
An object of the present invention is to provide an industrially advantageous process for producing aromatic dicarboxylic acids useful as raw materials for polymer materials such as polyester, polyamide, polybenzimidazole and polybenzoxazole. A first step of condensing a fluorenylidene bisphenol and a nitroaryl nitrile in the presence of an alkali compound to form an ether bond to obtain a corresponding dinitrile compound; And a second step of obtaining a corresponding dicarboxylic acid by solvolysis in the presence of the aromatic dicarboxylic acid. [Selection figure] None |
