ABSTRACT:
Corrosion metal contaminants are removed from a liquid composition comprising a carboxylic acid and/or an anhydride thereof, a rhodium carbonylation catalyst, and a carbonylation catalyst co-promoter by using a chelating resin selective for the removal of corrosion metals rather than carbonylation catalyst and co-promoter.
