Title:
CATALYST SYSTEM FOR SELECTIVE OLIGOMERIZATION OF ETHYLENE AND ETHYLENE OLIGOMERIZATION REACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/113748
Kind Code:
A1
Abstract:
Provided is a catalyst system for the selective oligomerization of ethylene, the catalyst system belonging to the field of catalysis technologies. The catalyst system comprises three components: a ligand a; a transition metal compound b, which is a compound of a metal from Groups IVB-VIII; and an activator c, which is a compound containing a Group IIIA metal, wherein the ligand a comprises at least one phosphine amine group as represented by general formula I, and bridging group A is a bridging group comprised of an alkyl group, an alkenyl group or an aryl group and a heteroatom in the backbone, with the heteroatom being one of silicon, tin, boron, phosphorus, nitrogen, oxygen or sulfur; and R1, R2, and R3 are respectively substituent groups on two phosphine amine groups, with R1, R2, and R3 being the same or different. The present invention has the beneficial effects of the catalyst system having a high activity, the selectivities for target products 1-hexene and 1-octene being high, the mass percentage content of C6-C8 linear α-olefins in the product being > 90%, and the catalyst being simple to synthesize, low in cost and long in life span.
