ABSTRACT OF THE DISCLOSURE: The present invention provides a process for producing olefin having a terminal double bond by trimerizing at least one monomer selected from a group consisting of ethylene, propylene, and 1-butene, which comprises using a catalyst comprising a product prepared from (1) component (A): a chromium compound represented by the formula [1] CrXmYn [1] wherein X represents carboxylic acid residue, 1,3- diketone residue, halogen atom or alkoxyl group, Y represents amine, phosphine, phosphine oxide, nitrosyl group or ether, m means an integer of from 2 to 4 and n means an integer of from 0 to 4, component (B): a heterocyclic compound having a pyrrole ring unit or an imidazole ring unit, and component (C): an aluminum compound represented by the formula [2] AlRkZ3-k [2] wherein R represents hydrogen atom or alkyl group having 1 to 10 carbon atoms, Z represents halogen atom and k means a real number of from 0 to 3, or (2) component (A) and component (B'): a heterocyclic compound having a pyrrole ring unit or an imidazole ring unit and further containing a bond between aluminum and nitrogen in the pyrrole ring or the imidazole ring. According to the present invention, olefin having a terminal double bond such as 1-hexene can be obtained effectively and conveniently, and the process is also good in the industrial application.
