摘要：
The present disclosure provides a process for recovering and recycling a catalyst from the mother liquor generated during the production of aromatic carboxylic acids. The process comprises treating the mother liquor with an alkyl aromatic compound and further treating the first aqueous layer obtained with an ionic liquid to obtain a catalyst rich aqueous mixture. The catalyst rich aqueous mixture is recycled to the oxidation reactor.
