Pd- and Rh-containing polymeric catalysts were studied in hydrogenation of acetylene alcohols and unsaturated ketones which are intermediates 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 Pd-containing polymer in the hydrogenation of long-chain acetylene alcohols was shown to occur. The supporting of Rh-containing polymer on Al2O3 also resulted in an increase of thermal stability of catalyst and increase of working time as compared with unsupported or traditional catalysts.
