ABSTRACT:
This invention relates to a method 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. The present invention also relates to an improved method for producing silver-exchanged macroreticular resins suitable for use in the present invention.
