A catalyst for trimerization of ethylene

摘要

A catalyst used for trimerization of ethylene into 1-hexene is descrobed, which comprises (i) a specific organometallic complex having a neutral multidentate ligand having a tripod structure, (ii) an alkylaluminoxane, and an optional ingredient selected from:
(iii) a halogenated inorganic compound,
(iv) a specific alkyl group-containing compound,
(v) a combination of a halogenated inorganic compound with a specific alkyl group-containing compound,
(vi) an amine compound and/or an amide compound, and
(vii) a combination of an amine compound and/or an amide compound with a specific alkyl group-containing compound.
