Procedure

2-(2-bromoethyl)naphthalene (120 g) was stirred in an ice bath while fuming sulfuric acid (50 g) was slowly added dropwise. After the dropwise addition, the mixture was stirred at 0° C. for 30 hours, whereby 2-(2-bromoethyl)naphthalenesulfonic acid and a plurality of isomers were obtained, and then separated and purified.
