Abstract

PURPOSE: To separate residue from the production of terephthalic acid into organic substance residue and an aqueous solution contg. catalyst by adding benzoic acid to the residue in a specified ratio by weight to p-alkyl substd. benzoic acids contained in the residue so as to extract and recover the catalyst.
