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2.58×105g/(molTi.h),α-烯烃选择性达80.72%。
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 he up to 2.58× 105g/ （molTi. h）, the selectivity of α-olefin such as 1-butene, 1-hexene, and 1-decene is 80. 72%.
