Abstract
248,339. Esseff Chemische Industrie-u. Handels Akt.-Ges. Feb. 25, 1925, [Convention date]. Sulphonhalogen-amide carboxylates.-Alkalineearth carboxvlates of aromatic sulphon-halogenalkali metal-amides are prepared by treating the corresponding sulphonamide carboxylic acids with alkaline-earth hypochlorite or similar alkaline earth halogen compound and substituting alkalimetal for alkaline-earth metal in the sulpho halo. gen amide group by treatment with an alkalimetal salt. In an example, p-sulphonamide benzoic acid is slowly added to a fairly clear solution of calcium hypochlorite, and after filtration the double sodium-calcium salt is precipitated by means of sodium acetate. The Specification as open to inspection unde. Sect. 91 (3) (a) comprises also a further example in which the sulphonamide of toluic acid is treated with calcium hypochlorite and sodium, then substituted for the calcium in the sulphon-chloramide group by means of sodium chloride. This subject-matter does not appear in the Specification as accepted.
