PCT No. PCT/JP93/01477 Sec. 371 Date Jun. 16, 1994 Sec. 102(e) Date Jun. 16, 1994 PCT Filed Oct. 14, 1993 PCT Pub. No. WO94/08924 PCT Pub. Date Apr. 28, 1994.A method for dimerizing an n-butene wherein a catalyst system is used which is produced in situ from an organonickel compound having no nickel-halogen bond, a triarylphosphine and/or a monoalkyldiarylphosphine, an organoaluminum compound and hydrogen. The resulting octenes are excellent as a raw material of alcohols for a plasticizer, and an excellent plasticizer can be obtained from alcohols having 9 carbon atoms produced by using the octenes.
