Kinetics of the Water Gas Shift Reaction Catalyzed by [Rh(COD)(4-Picoline)2]PF6 Immobilized On Poly(4-vinylpyridine)
ABSTRACT 	Kinetic studies of the water gas shift reaction have been carried Æt in the presence of [Rh(COD)(4-picoline)2]P F6, (COD = 1,5-cyclooctadiene) as catalyst, immobilized on poly(4-vinylpyridine) 2% cross linked with divinylbenzene in contact with a mixture of 80% aqueous 2-ethoxyethanol. The rhodium complex was anchored to the pyridine groups of the organic polymer. Analyses of kinetic results show a first order dependence on carbon monoxide pressure, a nonlinear dependence on rhodium total concentration and a segmented Arrhenius plot. These data are discussed in terms of a possible mechanism.
