Abstract
A method of producing an α-olefin low polymer, wherein an α-olefin is subjected to low polymerization in a solvent in the presence of a chromium catalyst and at least one inert gas. The proportion of the inert gas is maintained from 0.010 to 50.00% by volume in a gas phase part of a reactor, such that inert gas is discharged from the reactor and/or circulation piping when the proportion exceeds 50.00%. The chromium catalyst contains a chromium compound, at least one nitrogen-containing compound, an aluminum-containing compound, and optionally a halogen-containing compound. Unreacted α-olefin and solvent separated from a reaction liquid are circulated back into the reactor.
