PROBLEM TO BE SOLVED: To manufacture 1-hexene efficiently and highly selectively from ethylene. SOLUTION: A trimerization catalyst of ethylene is obtained by bringing a chromium complex having a neutral multidentate ligand, which has a tripod type structure represented by ACrBn (n is an integer of 1-3, A is a neutral multidentate ligand having a tripod type structure, Cr is a chromium atom and B is at least one component selected from the group consisting of a hydrogen atom, a halogen atom and a straight chain or branched alkyl group), into contact with an alkyl metal compound in a solution containing 10 vol.% or more of an alkane compound. This catalyst is used in the trimerization of ethylene. |
