PROCESS FOR DIMERIZATION OF ETHYLENE TO BUT-1-ENE USING COMPOSITION COMPRISING TITANIUM-BASED COMPLEX AND ALKOXY LIGAND FUNCTIONALIZED BY HETEROATOM

摘要

PROBLEM TO BE SOLVED: To provide a process for selective dimerization of ethylene to but-1-ene using a catalytic composition comprising at least one organometallic titanium complex.SOLUTION: The organometallic complex contains at least one alkoxy type ligand functionalized by a heteroatom selected from nitrogen, oxygen, phosphorus, sulfur, arsenic and antimony or by an aromatic group.SELECTED DRAWING: None
