OSMIUM LIQUID-PHASE CATALYSTS FOR HYDROGENOLYSIS OF SATURATED HYDROCARBONS AND HYDROGENATION OF ARENES

Article abstract of DOI:10.1007/BF01168057

Reduction of OsO4 by molecular hydrogen in alkane (cycloalkane) or benzene (toluene) solution produces small-lagand clusters of osmium of composition Os_1.5-2.5CH_0-2 with a particle size 10-40 Angstroem and a specific surface area of 34-46 m²/g.Hydrogenation of dry catalyst produces methane.The small-ligand osmium clusters obtained effectively catalyze hydrogenolysis of alkanes and cycloalkanes at 100-150 deg C and P_H2 = 5 MPa and hydrogenation of benzene at 20 deg C and P_H2 = 0.1 MPa.
