실험 절차

20.2 g of phenylphosphonic acid and 8.56 g of sulfotrioxide were mechanically mixed at 180° C. for 24 hr to prepare nz-sulfophenylphosphonic acid. After diluting with excess water, the mixture was added with 15% barium chloride. The precipitate was removed by filtering and excess dimethylether was added to extract unreacted phenyl phosphonic acid and obtain a m-sulfophenylphosphonic acid solution.
