NICKEL-CONTAINING ETHYLENE OLIGOMERIZATION CATALYST AND USE THEREOF

摘要

A process for the oligomerization of ethylene to a mixture of olefinic products having high linearity is provided, by using a catalyst comprising a reaction product of a simple divalent nickel salt; a boron hydride reducing agent; a water soluble base; a ligand selected from an o-dihydrocarbylphosphinobenzoic acid and alkali metal salt thereof; and, a phosphite.
