Procedure

8-Anilino-1-octanesulfonic acid sodium salt (10.0 g, 0.5 mol) is dissolved in aqueous 0.5 M HCl solution (30 mL) and acetonitrile (400 mL) is added to the solution. The solution is filtered and the filtrate is kept in a refrigerator overnight to obtain 8-anilino-1-octanesulfonic acid as white precipitates. The precipitates are collected by filtration, dissolved in water, neutralized by aniline, and then concentrated under reduced pressure to give a white solid.
