The present invention relates to a process for oligomerization of an olefin, comprising the steps of: introducing an oligomerization transition metal catalyst, an olefin monomer, and a solvent into a reactor to carry out an oligomerization reaction of olefin to produce an oligomer; Wherein the reaction product of the oligomerization reaction contains at least one of functional groups including at least one selected from the group consisting of oxygen, phosphorus, nitrogen, and sulfur, and a catalyst deactivator having a number average molecular weight of 400 or more is charged, Deactivating; Distilling and separating the oligomer from the distiller; And separating the catalyst deactivator into the bottom of the distillation column. |
