METHODS FOR OLIGOMERIZING OLEFINS WITH CHROMIUM PYRIDINE MONO-OXAZOLINE CATALYSTS

摘要

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a chromium based catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl mono-oxazoline compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1 -hexene, 1 - octene, or mixtures of 1 -hexene and 1 -octene.
