ABSTRACT OF THE DISCLOSURE There is disclosed a highly selective hydrogenation catalyst composition synthesized by adding an organometallic reducing agent, e.g., triethylaluminum, to a transition metal compound, e.g., nickel (II) octoate. The catalyst composition is synthesized either by adding the organometallic reducing agent to the transition metal compound, in that order, as rapidly as possible, or by adding the reducing agent and the transition metal compound, separately but substantially simultaneously, at substantially constant molar ratios to the catalyst synthesis vessel. m e catalyst composition is substantially more selective in hydrogenating mono-substituted and symmetrically disubstituted polymer double bonds in the presence of unsymmetrically disubstituted double bonds and double bonds having three or more substituents, and substantially more stable over extended periods of time at ambient conditions than prior art catalysts.
