Abstract: Disclosed herein is a catalyst for especially for selective hydrogenation among a carbon-carbon double bond, a carbonyl group and an aromatic unsaturated ring such as benzene. The catalyst comprising platinum and zeolite can be employed for selectively hydrogenating the carbon-carbon double bond and the carbonyl group of an organic compound without the hydrogenation of the aromatic unsaturated. The catalyst comprising the platinum supported on a support which comprises powders of an inorganic component to which is supported polyethylene glycol or an ethylvinylbenzene-divinylbenzene copolymer can be employed for selectively hydrogenating the carbon-carbon double bond of an organic compound without the hydrogenation of the carbonyl group and the aromatic unsaturated ring.
