CATALYTIC-HYDROGENATION PROPERTIES OF PD-CONTAINING AND RH-CONTAININGPOLYMERS IMMOBILIZED ON AL2O3

Pd- and Rh-containing polymeric catalysts were studied in hydrogenatio n of acetylene alcohols and unsaturated ketones which are intermediate s in production of vitamins and fragrant substances. The influence on catalytic properties of supporting the prepared polymers on Al2O3 was investigated. The increase of stability and selectivity of supported P d-containing polymer in the hydrogenation of long-chain acetylene alco hols was shown to occur. The supporting of Rh-containing polymer on Al 2O3 also resulted in an increase of thermal stability of catalyst and increase of working time as compared with unsupported or traditional c atalysts.
