Catalyst composition suitable for the dimerization or codimerization of alpha-olefins.

摘要

A catalyst composition consisting essentially of a molded article comprising an anhydrous inorganic potassium compound and metallic sodium and metallic potassium dispersed on the surface of the molded article, said molded article further containing 0.7 to 3% by weight, based on the weight of the inorganic potassium compound, of elemental carbon, the atomic ratio of metallic sodium to metallic potassium being in the range of from 20:80 to 90:10. This catalyst composition is useful for the dimerization or codimerization of alpha-olefins.
