The present invention provides that the loss of 3,4-dichloro-1-butene as a raw material or 1,2,3,4-tetrachlorobutane as a product is not easily generated, and 1,2,3, can be produced stably and economically, Method and device for producing 4-tetrachlorobutane and 1,2,3,4-tetrachlorobutane. After the reaction liquid (1) containing 3,4-dichloro-1-butene was stored in the reaction container (11), chlorine gas was supplied to the gas phase part (2) in the reaction container (11) to make 3,4- Dichloro-1-butene reacts with chlorine gas to produce 1,2,3,4-tetrachlorobutane. |
