REMOVAL OF HALIDES FROM CARBOXYLIC ACIDS

摘要

The present invention relates to a method for producing silver-exchanged macroreticular resins suitable for removing halides from liquid carboxylic acid contaminated with a halide impurity by contacting the liquid halide-contaminated acid with a silver(I)-exchanged macroreticular resin. The halide reacts with the resin-bound silver and is removed from the carboxylic acid stream.
