  The present disclosure relates to a process for producing ethylene oligomers and more particularly, to a process for oligomerizing ethylene by recycling butene, hexene, and octene in an ethylene oligomerization reaction with a catalyst system including a transition metal or transition metal precursor, a ligand with a backbone structure expressed by the following Chemical Formula 1, and a co-catalyst. [Chemical Formula 1] R1—O—Y—O—R2 or R1—OC(═O)—Y—C(═O)OR2 Herein, R1, R2 are each independently hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl, or substituted heterohydrocarbyl, and Y represents a group connecting O or C(═O)O and is hydrocarbyl, substituted hydrocarbyl, hetero hydrocarbyl, or substituted heterohydrocarbyl. According to the oligomerization method of the present disclosure, in the distribution of the produced α-olefins, C10″-C12″ α-olefins care highly distributed, the produced α-olefins have a remarkably high purity.

  本公开涉及一种生产乙烯低聚物的工艺，更具体地说，涉及一种通过在乙烯低聚反应中回收丁烯、己烯和辛烯而使乙烯低聚的工艺，该催化剂体系包括过渡金属或过渡金属前体、具有以下化学式1表示的骨架结构的配位体和助催化剂。[化学式 1] R1-O-Y-O-R2 或 R1-OC(═O)-Y-C(═O)OR2 这里，R1、R2 各自独立地为烃基、取代的烃基、杂烃基或取代的杂烃基，Y 代表连接 O 或 C(═O)O 的基团，并且是烃基、取代的烃基、杂烃基或取代的杂烃基。根据本公开的低聚方法，在生成的α-烯烃的分布中，C10″-C12″ α-烯烃的分布较多，生成的α-烯烃具有显著的高纯度。
