VERFAHREN ZUR VERBESSERUNG DER PRODUKTIVITÄT EINER KATALYSATORLÖSUNG DURCH ENTFERNUNG VON METALLISCHEN VERUNREINIGUNGEN

摘要

A process for treating low water content carbonylation catalyst solutions which contain a rhodium component and an alkali metal component to remove metallic corrosion products is disclosed. The process comprises contacting the catalyst solution with an ion exchange resin, preferably in the lithium form, and a sufficient amount of water to decrease the concentration of alkali metal ions to optimize removal of corrosion metal products.
