METHODS FOR OLIGOMERIZING OLEFINS WITH CHROMIUM PYRIDINE PHOSPHINO CATALYSTS

摘要

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl phosphino 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.
