新型吡啶类配体/Cr（Ⅲ）/MAO催化乙烯齐聚
Ethylene Oligomerization Catalyzed by Pyridine-based Ligands/Cr(Ⅲ)/MAO
摘要
Abstract
In order to find novel catalyst for ethylene oligomerization,two pyridine-based ligands,N-(diphenylphosphino)-pyridin-2-amine(L1)and N-(diphenylphosphino)-6-methylpyridin-2-amine(L2)were synthesized and characterized .The corresponding chromium complexes ,C1 and C2 ,were synthesized by combining CrCl3(THF)3 with L1 and L2 respectively.The catalytic properties of C1/MAO and C2/MAO for ethylene oligomerization were investigated systemati-cally.It was revealed that the catalytic activity of C1/MAO in toluene reached 4.79×105 g/(mol·h)and the products were linearα-olefins with a wide range of distribution.In cyclohexane,it had good selectivity towards 1-octene and 1-hexane, which is up to 88.24%, in total.关键词
