US Patent 10471416 Method for oligomerizing an olefin

A method for oligomerizing an olefin comprising performing a multimerization reaction of an olefin in the presence of an oligomerization catalyst system comprising a ligand compound, a transition metal compound and a co-catalyst, and controlling a reaction temperature during the multimerization reaction in a range of 30 to 150° C., such that a product of the multimerization reaction comprising 1-hexene and 1-octene has a predetermined value of a weight ratio of 1-hexene and 1-octene selected from a range of 1:0.5 to 1:7.
