Abstract
Provided are a method and an apparatus for producing 1,2,3,4-tetrachlorobutane that are unlikely to lose 3,4-dichloro-1-butene as the material or 1,2,3,4-tetrachlorobutane as the product and can be stably and economically produce 1,2,3,4-tetrachlorobutane. A reaction liquid () containing 3,4-dichloro-1-butene is placed in a reaction container (), then chlorine gas is supplied to a gas phase () in the reaction container (), and the 3,4-dichloro-1-butene is reacted with the chlorine gas to give 1,2,3,4-tetrachlorobutane.
