Abstract

For obtaining salts of sulphanilamide, useful for various therapeutic purposes, with non-volatile acids, i.e. acids which do not escape with the vapours of an aqueous solvent, the sulphanilamide is dissolved in an organic solvent free from, or containing only a little, water, and the calculated quantity of non-volatile inorganic or organic acids is added. Reaction is completed if necessary by boiling under reflux and the salts obtained by filtration or by vaporization of the solvent used. Suitable solvents are acetone or alcohol. Examples describe the preparation of (1) sulphanilamide monophosphate, (2) sulphanilamide o-hydroxyquinoline - m - sulphonate, (3) sulphanilamide salicylate, (4) sulphanilamide acetylsalicylate.
