摘　　要：合成了配合物氯化2-乙酰基-1,10-菲咯啉缩2,6-二乙基苯胺合铁(Ⅱ),以甲苯为溶剂,甲基铝氧烷为助催化剂,催化乙烯齐聚制备线型α-烯烃。催化剂表现出高活性和对α-烯烃的高选择性。考察了反应温度、n(Al)/n(Fe)、反应压力和催化剂浓度等对催化剂活性和齐聚产物分布的影响。The authors synthesized 2-acetyl- 1,10-phenanthroline（2,6-diethylanil）Fe （ II ） complex. Linear α-olefins were prepared via ethylene oligomerization with the complex as main catalyst and methylaluminoxane （MAO） as cocatalyst in toluene. The catalyst had high activity and selectivity to α-olefins. The effects of the reaction temperature, reaction pressure, molar ratio catalytic activity and the carbon number distribution of of aluminum to iron and catalyst concentration on the oligomers were studied.
