Complexs of Poly(1-vinylimidazole-co-methyl methacrylate) and Copper Ion as Catalysts for the Oxidation of Ethylbenzene

Abstract:

This paper was reported a polymeric support metal catalyst and its application in oxidation of ethylbenzene with molecular oxygen. The Poly(1-vinylimidazole-co-methyl methacrylate) copolymer (PVM) was directly mixed with copper sulfate solution to prepare the catalyst of Cu(II)-PVM. The appropriate reaction temperature and amount of catalyst were 130°C and 0.2g. Recycling studies indicated that the catalyst could be recycled at least four times without significant decrease of catalytic activity.
