一种含正丙酰基取代的1，10-菲咯啉缩胺合铁(Ⅱ)配合物的乙烯齐聚催化剂组合物
摘要：
本发明提供一种乙烯齐聚催化剂组合物，包括下式(I)的正丙酰基取代的1，10-菲咯啉缩胺合铁(II)配合物主催化剂和三乙基铝助催化剂，其中所述助催化剂中金属铝与主催化剂中心金属铁的摩尔比为30至900。本发明还提供一种采用上述催化剂组合物的乙烯齐聚方法。本发明中，作为助催化剂的三乙基铝价格低廉，仅为甲基铝氧烷价格的几十分之一，且助催化剂用量大幅降低，本发明的催化剂催化乙烯齐聚具有较好的催化活性，使得乙烯齐聚反应成本大幅下降；且齐聚产物中线性α-烯烃的选择性较高；齐聚产物分布更加合理；不会产生乙烯聚合物；因此本发明工业化前景广阔。
摘要（英）：

The invention provides an ethylene oligomerization catalyst composition. The ethylene oligomerization catalyst composition comprises a main catalyst of a 1, 10-phenanthroline amino-iron (II) complex which is substituted by propionyl in a formula (I) and a catalyst promoter of triethyl aluminum, wherein the molar ratio of the metallic aluminium of the catalyst promoter to the central metallic aluminium of the main catalyst is between 30 and 900. According to the ethylene oligomerization catalyst composition, the triethyl aluminum which is used as the catalyst promoter is low in price and only accounts for a small percentage of the price of methylaluminoxane, and the usage of the catalyst promoter is greatly reduced, the catalyst has good catalytic activity of catalyzing ethylene oligomerization, so that the ethylene oligomerization reaction cost is greatly lowered; the selectivity of linear alpha-olefin in an oligomerization product is high; the oligomerization product is distributed reasonably; polyvinyl cannot be generated; and thus, the ethylene oligomerization catalyst composition has a wide industrial prospect.
