Abstract
Kinetic studies of the water gas shift reaction have been carried AE t in t he presence of [Rh(COD) (4-picoline)(2)] PF6, (COD = 1,5-cyclooctadiene) as catalyst, immobilized on poly(4-vinylpyridine) 2% cross linked with diviny lbenzene in contact with a mixture of 80% aqueous 2-ethoxyethanol. The rhod ium complex was anchored to the pyridine groups of the organic polymer. Ana lyses of kinetic results show a first order dependence on carbon monoxide p ressure, a nonlinear dependence on rhodium total concentration and a segmen ted Arrhenius plot. These data are discussed in terms of a possible mechani sm.
