【Abstract】 A review is provided of the recent progress in research of catalysts for dimerization of propylene.The effects of active central atoms,co-catalysts,and auxiliary phosphine ligands on the reactivity of catalysts and selectivity of products are discussed,and the catalytic reaction mechanisms for propylene dimerization under homogeneous and heterogeneous catalytic conditions are compared.In the meantime,with a view to the concept of shape selective catalysis and the advantages of ionic liquid,a new approach is put forward to develop catalysts for propylene dimerization.更多还原
