Abstract

PURPOSE: To recover a bromine cpd. used as a catlayst component and a heavy metal catalyst whose activity has been hardly reduced at a low cost by concentrating mother liquor after separating and recovering benzene polycarboxylic acids and then treating the water extract of the concentrate with a strongly basic anion exchange resin.
