Zusammenfassung:	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.
