A new P-N-P ligand is useful in ethylene oliogomenzation. The ligand is characterized by having at least one aromatic fiuorocarbyl alkoxide group bonded to a P atom, hi combination with 1) a source of chromium and 11) an activator such as methylalumoxane, the ligand of this invention may be used to prepare an oligomer product that contains a mixture of high purity alpha olefins, hi a preferred emobidment, the ligand of this invention enables a selective oligomerization in which the majority of the liquid product is a mixture of hexene and octene. The amount of byproduct polymer that is produced in preferred oligomerization reactions is advantegeously low.
一种新的P-N-P配体在乙烯寡聚化中很有用。该配体的特征是至少有一个芳香氟代碳基烷氧基团与P原子结合,与1)铬源和11)活化剂(如甲基铝氧烷)结合,本发明的配体可用于制备含有高纯度α烯烃混合物的寡聚物产品。在一个首选实施例中,本发明的配体使得选择性寡聚化成为可能,其中大部分液态产品是己烯和辛烯的混合物。在首选寡聚化反应中产生的副产物聚合物的量是有优势的低。
