Methods for manufacturing olefin dimers, catalysts for olefin dimerization, and methods for manufacturing the same.

Abstract

One embodiment of the present invention provides a method for manufacturing an olefin dimer with high olefin conversion rate and high olefin dimer yield in an olefin dimerization reaction, a catalyst for olefin dimerization, and a method for manufacturing the same. The method for manufacturing an olefin dimer includes a step of dimerizing an olefin containing an olefin with 3 to 10 carbon atoms in the presence of an olefin dimerization catalyst. The catalyst comprises an alkali metal (A), a compound (B) represented by BnX (where B is Na or K, X is CO3, SO4, SiO3, F, Cl, or Br, and n is an integer of 1 or 2 determined by the valence of X), and a transition metal element (C). The content of the transition metal element (C) is 0.5% by mass or more and less than 1.0% by mass relative to 100% by mass of the catalyst.
