(57) [Abstract] [Purpose] A method for producing an α-olefin low polymer using a chromium-based catalyst, which prevents the precipitation of metal components, in particular α-containing mainly 1-hexene from ethylene. Provided is an industrially advantageous process for producing an α-olefin low polymer, which is capable of producing an olefin low polymer with high yield and high selectivity. A catalyst system comprising at least a combination of a chromium compound (a), at least one compound (b) selected from the group of amines, amides and imides, and an alkylaluminum compound (c) is used, and α in a solvent is used. -Low polymerization of olefin, then after adding a compound soluble in a solvent and having a ligand-forming ability to chromium to the reaction solution, Each component is separated by distillation from the reaction solution. |
