摘要： A method of recovering the catalyst in active form from the acetic mother liquors from the synthesis of terephthalic acid. From said mother liquors, after removal of water, there is removed by evaporation an amount of from 70 to 90% of the CH.sub.3 COOH present therein. The concentrated liquor is cooled below 60.degree. C. and the solid which precipitates is collected and recycled for reuse in the systhesis. The liquid phase is extracted with water or with an aqueous acetic acid solution in the presence of particular coadjuvants such as isobutyl acetate, and the aqueous phase, which contains the recovered catalyst, is recycled to the original synthesis.
