Process for the Removal of Catalytic Metals and Promoter Metals from Carbonylation Process Streams |
摘要 |
A process for the selective removal of Group VIII carbonylation catalyst metals and/or promoter metals from liquid compositions comprising a carbonylation product, the Group VIII carbonylation catalyst metals and/or promoter metals, corrosion metals and optionally alkali or alkaline earth metals. The process comprises contacting the liquid composition with a chelating resin having thiourea functional groups. The process is suitable for treating process streams obtained in the production of carboxylic acids and/or carboxylic anhydrides.
