Estimating the term…
There is provided a method of producing 1,2,3,4-tetrachlorobutane capable of stably and economically producing 1,2,3,4-tetrachlorobutane. A reactant solution (1) containing 3,4-dichloro-1-butene is charged in a reaction vessel (11) having an inner surface, to be brought into contact with the reactant solution (1), made of a metal and a chlorine gas is introduced into the reactant solution (1) to perform a reaction between 3,4-dichloro-1-butene and the chlorine gas to produce 1,2,3,4-tetrachlorobutane. The reaction is performed while carrying out an operation of taking out at least a portion of the reactant solution (1) from the reaction vessel (11), filtering the reactant solution (1) thus taken out to remove a solid matter, and returning the filtered reactant solution (1) into the reaction vessel (11).
A process for producing 1,2,3,4-tetrachlorobutane by charging a reactant solution containing 3,4-dichloro-1-butene in a reaction vessel having an inner surface made of a metal, to be brought into contact with the reactant solution and introducing a chlorine gas into the reactant solution to cause a reaction between the 3,4-dichloro-1-butene and the chlorine gas, the process comprising performing the reaction while taking out at least a portion of the reactant solution from the reaction vessel, filtering the portion to remove a solid matter, and returning the filtered reactant solution to the reaction vessel.
