Ethylene tetramerization catalyst systems and method for preparing 1-octene using the same
摘要：
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).
摘要（中）：

本文公开了一种以高活性和高选择性制备1-辛烯的方法，同时通过使用包含过渡金属或过渡金属前体，助催化剂和PCCP骨架结构配体的铬基催化剂体系，通过乙烯四聚来稳定维持反应活性， 由（R1）（R2）P-（R5）CHCH（R6）-P（R3）（R4）表示。
