The present invention relates to a method for chlorinating an aromatic compound and, more specifically, to a method for chlorinating an aromatic compound to prevent the phenomenon of decreased responsiveness due to foam generation, and to prevent counterflow of a fluid.

By means of the method for chlorinating an aromatic compound according to the present invention, a plurality of column-type reactors are connected in series so that reaction products produced in a former reactor are inserted to a latter reactor, and chlorine gas is inserted in equal measure at the bottom of each reactor. Accordingly, a chlorination reaction occurs in each of the reactors, and hydrogen chloride gas generated in each of the reactors is exhausted from each of the reactors.
