There was furnished a 300-ml four-necked flask equipped with a stirrer, condenser, and thermometer, which was charged with 80 g of 1,2-ethylene dichloride and 51 g (0.22 mol) of 1,2-dibromobenzene. While moderately passing nitrogen gas, 38 g (0.29 mol) of 60% fuming sulfuric acid was added dropwise, and reaction was effected at 70° C. for 2 hours. The reaction solution was cooled, followed by filtration and drying, obtaining 51 g of crude 3,4-dibromobenzenesulfonic acid.
