AQUEOUS PHASE HYDROFORMYLATION OF PROPENE CATALYZED OVER RHODIUM COMPLEXES IMMOBILIZED ON THE POLY(STYRENE-DIVINYLBENZENE) COPOLYMER CONTAINING CH2P(C6H4SO3H)2 GROUPS

Abstract

RhCl3.3H2O and RhCl(CO) (PPh3)2 were immobilized on the poly (styrene-divinylbenzene) copolymer containing -CH2P (C6H4SO3H)2 (diphenylphosphine disulfonate) groups to give active and stable hydroformylation catalysts in an aqueous phase. With these catalysts, propene undergoes rapid hydroformylation. The hydroformylation of propene, using the above catalysts, has been investigated at 373 K and in a pressure range of 5 to 50 atm in an aqueous medium. The activity of CAT 1 increased with the increase in the total pressure of carbon monoxide and hydrogen and the rate of hydroformylation reached a maximum at the atomic ratio of phosphine to rhodium of 8.7.
