FREMGANGSMADE TIL FREMSTILLING AF SODESTOFFET 6-METHYL-3,4-DIHYDRO-1,2,3-OXATHIAZIN-4-ON-2,2-DIOXID-KALIUM

摘要

The potassium salt practically free of fluoride of 6-methyl-3,4-dihydro-1,2,3-oxathiazin-4-one-2,2-dioxide is prepared by cyclization of acetoacetamide-N-sulfofluoride with at least two moles potassium hydroxide, potassium methylate or a mixture of potassium hydroxide and potassium methylate per mole of sulfofluoride in methanol as solvent containing less than 50 % by weight of water at a temperature of from -20 DEG to +60 DEG C and separating the crystalline potassium salt of the oxathiazinone dioxide from the reaction solution. The compound obtained has a pure sweet taste.
