Document Type and Number:
Japanese Patent JPH0125741
Kind Code:
B2
Abstract:
Crystalline salts of acetoacetamide-N-sulfofluoride are prepared by reacting amidosulfofluoride H2NSO2F with diketene in the presence of inorganic bases, preferably alkali metal carbonates and/or hydrogencarbonates, in particular potassium carbonate, in an inert organic solvent. The salts can be further processed with further base, for example with methanolic KOH, into salts of 6-methyl-3,4-dihydro-1,2,3-oxathiazin-4-one-2,2-dioxide; the potassium salt, in particular, is important for use as a sweetener ("Acesulfame").
