Abstract:
A carbonylation process comprising:(a) carbonylating a reactant in the presence of a Group VIII metal catalyst component and an alkyl halide promoter component to form a reaction mixture in a reactor; (b) supplying a stream of the reaction mixture to a flasher, coupled to the reactor, to separate the stream of the reaction mixture into a liquid recycle stream and a product stream; (c) contacting the product stream with a polymeric resin comprising nitrogen containing heterocyclic repeat units operative to sequester, on the polymeric resin, at least a portion of the Group VIII metal catalyst component present in the product stream; and (d) recovering the at least a portion of the Group VIII metal component by separating the at least a portion of the Group VIII metal component from the polymeric resin.
