Method for producing catalyst composition for hydrogenation and catalyst composition for hydrogenation

A method for producing a catalyst composition for hydrogenation, wherein: (A): a titanocene compound represented by following general formula (1): wherein R 5 and R 6 represent a group selected from the group consisting of hydrogen, a hydrocarbon group having 1 to 12 carbon atoms, an aryloxy group, an alkoxy group, a halogen group and a carbonyl group, and may be the same or different, and R 1 and R 2 represent a group selected from the group consisting of hydrogen and a hydrocarbon group having 1 to 12 carbon atoms, and may be the same or different, provided that R 1 and R 2 represent are not all hydrogens or all hydrocarbon groups having 1 to 12 carbon atoms; (B): a compound containing at least one element selected from the group consisting of elements Li, Na, K, Mg, Zn, Al, and Ca; and (C): an unsaturated compound are used, and the method has: a force application step of applying a shearing force at a shearing rate of 1000 (1/s) or more to at least component (A); and a step of mixing components (A), (B), and (C).
