Catalyst composition and process for preparing linear alpha-olefins

摘要

The present invention relates to a catalyst composition for the oligomerization of ethylene, comprising a transition metal compound of the general formula MX m (OR') 4-m or MX m (OOCR') 4-m , wherein R' is an alkyl, alkenyl, aryl, aralkyl or cycloalkyl group, X is chlorine or bromine and m is from 0 to 4 and a reaction product of an organoaluminium compound and a cyclic amide, preferably 2-pyrrolidone; as well as to a process for preparing linear alpha-olefins utilizing this catalyst composition.
