Abstract

A simple and efficient catalyst removal system has been developed in the cobalt–salen-catalyzed copolymerization of propylene oxide with carbon dioxide. The present system requires no prior modification of the catalyst, and the removal is achieved by simple addition of myristic acid, followed by organic liquid–liquid phase separation.
