ABSTRACT:
A process for removing iodide derivatives from liquid acetic acid and/or acetic anhydride comprises contacting the liquid acetic acid and/or acetic anhydride with a strong acid cation exchange resin having from about 4% to about 12% crosslinking, a surface area in the proton exchanged form of less than 10m.sup.2 g.sup.-1 after drying from the water wet state and a surface area of greater than 10m.sup.2 g.sup.-1 after drying from a wet state in which water has been replaced by methanol. The resin has at least one percent of its active sites converted to the silver form preferably from 30 to 70 percent.
