摘要

合成了三种PNP配体，并与Ti（IV）作用形成催化剂，利用核磁共振氢谱、元素分析及质谱对配体及催化剂进行了结构表征。在助催化剂甲基铝氧烷（MAO）存在的条件下，催化乙烯齐聚。试验结果表明：钛（IV）剂催化活性最高可达2.58×10

g/（molTi·h），α-烯烃选择性达80.72%。

Abstract

Three novel catalyst systems which were composed by PNP ligands/Ti(IV)/methylaluminoxane (MAO) has been synthesized

and the ligand and catalyst structure has been characterized by NMR

elemental analysis and mass spectrometry.The catalyst performance which showed during ethylene oligomerization test indicate: the titanium-based catalyst activity could be up to 2.58×10

g/ (molTi·h)

the selectivity of α-olefin such as 1-butene

1-hexene

and 1-decene is 80.72%.
