Kind Code:

A1

Abstract:

Provided is a 1,2,3,4-tetrachlorobutane production method that enables stable and economic production of 1,2,3,4-tetrachlorobutane. According to the present invention, 1,2,3,4-tetrachlorobutane is produced by: placing a reaction solution (1) containing 3,4-dichloro-1-butene in a reaction container (11) in which the inner surface that makes contact with the reaction solution (1) is formed of a metal; and introducing chlorine gas into the reaction solution (1) so as to cause a reaction between 3,4-dichloro-1-butene and chlorine gas. The reaction is conducted while performing an operation of: extracting at least a portion of the reaction solution (1) in the reaction container (11); subjecting the extracted reaction solution (1) to filtration so that solid matter is removed therefrom; and returning the filtered reaction solution (1) to the reaction container (11).
