Hydrogenation of Unsaturated Hydrocarbons on Platinum and Palladium Catalysts Encapsulated in Mesoporous Bakelites

Аннотация

Syntheses are reported for catalysts derived from platinum and palladium nanoparticles supported on a mesoporous phenol formaldehyde polymer modified by an ionic liquid. These catalysts are used for the hydrogenation of unsaturated compounds, specifically, acyclic and cyclic isoprenoids: isoprene, 2,5 – dimethyl–2,4–hexadiene, limonene, α –terpinene, γ –terpinene, as well as phenylacetylene, transstilbene, and 1,4–diphenyl–1,3–butadiene. High activity was found for these catalysts in hydrogenation reactions. The palladium catalysts were more active than their platinum analogs. The products of complete hydrogenation predominate in the hydrogenation of isoprenoids on the palladium catalysts, while monoene products predominate in the reactions on platinum catalysts.
