A catalyst composition for hydrogenation, which contains components (A)-(D), with the mass ratio ((C)/(A)) being 0.1-4.0 and the mass ratio ((D)/(A)) being 0.01-1.00. (A) a titanocene compound represented by formula (1) (In formula (1), each of R5 and R6 represents one group selected from among a hydrogen atom, a C1-C12 hydrocarbon group, an aryloxy group, an alkoxy group, a halogen group and a carbonyl group; and each of R1 and R2 represents one group selected from among a hydrogen atom and a C1-C12 hydrocarbon group, excluding the cases where both R1 and R2 are hydrogen atoms or C1-C12 hydrocarbon groups.) (B) a reducing agent which is composed of a compound containing an element that is selected from among Li, Na, K, Mg, Zn, Al and Ca (C) an unsaturated compound having a molecular weight of 400 or less (D) a polar compound. |
