摘　　要：合成了氯化2-乙酰基-1,10-菲咯啉缩2,6-二氯苯胺合铁(Ⅱ),探讨了它与甲基铝氧烷(MAO)组成的二元催化体系催化乙烯齐聚的性能。实验发现,该体系催化乙烯齐聚活性高,对α-烯烃选择性好,而且反应温度、n(Al)/n(Fe)和反应压力等因素对催化活性和齐聚产物分布有较大影响。Complex 2-acetyl-1,10-phenanthroline（2,6-dichloroanil）FeCl2 was synthesized.Ethylene oligomerization was carried out by using the catalyst activated with MAO in toluene.The results show that the catalyst has high activity and selectivity to α-olefins.Some factors including reaction temperature,reaction pressure and mole ratio of Al to Fe have effect on the catalytic activity and distribution of α-olefin.
