TRIMERIZATION CATALYST FOR OLEFIN

摘要

Disclosed is a catalyst containing (A) a tantalum compound and (B) an organic metal compound having at least one group selected from the following (1)-(5): (1) branched or cycloalkyl-substituted primary alkyl groups having 4-15 carbon atoms; (2) aryl-substituted primary alkyl groups having 7-15 carbon atoms; (3) 3-alkenyl groups having 4-15 carbon atoms; (4) secondary alkyl groups having 3-15 carbon atoms which may be substituted by an aryl group or cyclic alkyl groups having 3-15 carbon atoms; and (5) secondary alkenyl groups having 4-15 carbon atoms. The catalyst exhibits good olefin trimerization activity.
