Abstract
A method for producing an olefin dimer, including a step of subjecting an olefin containing an olefin having from 4 to 10 carbon atoms to a dimerization reaction in the presence of an olefin dimerization catalyst containing a compound (B) represented by BnX (wherein 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 a valence of X), and an alkali metal (D), a content ratio of which is in a specific range, and an olefin dimerization catalyst in which a pore diameter and a volume of pores of the compound (B) are within specific ranges.

A method for producing an olefin dimer, the method comprising a step of subjecting an olefin comprising an olefin having from 4 to 10 carbon atoms to a dimerization reaction in the presence of an olefin dimerization catalyst comprising a compound (B) represented by BnX, wherein 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 a valence of X, and an alkali metal (D), wherein the compound (B) has a volume of pores with a pore diameter of from 0.05 μm to 10 μm of from 0.01 mL/g to 0.09 mL/g, and a content ratio of the alkali metal (D) is from 3.0 to 12.5% by mass based on 100% by mass of the total amount of the compound (B) and the alkali metal (D).
(canceled)
An olefin dimerization catalyst, comprising:
- a compound (B) represented by BnX, wherein 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 a valence of X;
