Abstract

1519462 Hydrogenating olefins UNISEARCH Ltd 10 July 1975 1975 [10 July 1974] 29060/75 Heading C5E [Also in Division C3] Olefins are hydrogenated in the presence of a heterogeneous catalyst comprising a homogeneous catalyst molecule bound to a substrate obtained by irradiation graft polymerizing a monomer onto a metallic or polymeric substrate, the monomer containing an active substituent which is a halogen or nitrogen-containing group and having either an aromatic group or a carbon chain of at least two carbon atoms between the active substituent and the point of attachment to the substrate. In Examples cyclohexene is hydrogenated in the presence of catalysts prepared by reacting rhodium trichloride with a polypropylene/p-nitrostyrene graft polymer or a reduction product thereof, or by reacting rhodium (tris-triphenylphosphine) (carbonyl) chloride with a polypropylene/p-chlorostyrene graft polymer or a reduced polypropylene/p-nitrostyrene graft polymer.
