실험 절차
The preparation was undertaken as a modification of the process for forming 3-carboxybenzenesulfonyl chloride as reported in J. Chem. Soc. (C), page 11 et seq. (1968) by R. J. W. Cremlyn. Phenylphosphonic acid was added in portions to chlorosulfonic acid; about 10 moles of chlorosulfonic acid per mole of phenylphosphonic acid were employed. The initial mixing step was exothermic, causing the temperature of the mixture to rise to about 90° C. After completion of the addition of the phenylphosphonic acid to the chlorosulfonic acid, the reaction mixture was heated to about 140° C. for about two hours. Reaction proceeded according to the equation ##STR5## Attempts to lower the molar ratio of chlorosulfonic acid: phenylphosphonic acid, by addition of sodium chloride (to remove sulfuric acid from the reaction mixture), caused uncontrollable frothing.
