| 摘要 |
The present invention pertains to a method for producing an α-olefin oligomer by conducting an oligomerization reaction of an α-olefin in the presence of a solvent and a catalyst containing a transition-metal-containing compound, an aluminum-containing compound, and hydrocarbons having two or more carbon atoms substituted by halogen atoms, wherein: the method for producing an α-olefin oligomer is provided with a reaction step, a purification step, and a cycling step for cycling unreacted raw-material α-olefin and solvent from the purification step to the reaction step; and the amount, supplied from the cycling step to the reaction step, of olefin having two or more carbon atoms substituted by halogen atoms is within a range from 0.1 to less than 200 (molar ratio) relative to the amount of transition metal in the reaction step. |
