Disclosed herein is a method of preparing 1-octene at high activity and high selectivity while stably maintaining reaction activity by tetramerizing ethylene using a chromium-based catalyst system comprising a transition metal or a transition metal precursor, a cocatalyst, and a P—C—C—P backbone structure ligand represented by (R1)(R2)P—(R5)CHCH(R6)—P(R3)(R4).
本文公开了一种利用铬基催化剂体系制备 1-辛烯的方法,该催化剂体系由过渡金属或过渡金属前体、助催化剂以及由 (R1)(R2)P-(R5)CHCH(R6)-P(R3)(R4) 表示的 P-C-C-P 主干结构配体组成,通过乙烯四聚合,在稳定保持反应活性的同时实现高活性和高选择性。
