摘　　要：合成了配合物氯化2-乙酰基-1,10-菲咯啉缩2,6-二异丙基苯胺合铁(Ⅱ),以甲苯为溶剂,甲基铝氧烷(MAO)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)和反应压力等对催化剂活性和齐聚产物分布的影响。The complex 2-acetyl-1,10-phenanthroline（2,6-diisopropylanil）FeCl2 was synthesized.Ethylene oligomerizations were carried out by using the catalyst activated with MAO in toluene.The catalyst had high activity and selectivity to α-olefins.The effects of reaction temperature,ethylene pressure,and the mole ratio of aluminum on the catalytic activity and the distribution of α-olefins were investigated.
