Abstract: 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.

Abstract: 6-Methyl-3,4-dihydro-1,2,3-oxathiazin-4-one-2,2-dioxide and the nontoxic salts thereof are prepared by reacting acetone and fluorosulfonyl isocyanate in a molar proportion of from 14:1 to 150:1 at a temperature of from 0 DEG to 60 DEG C, distilling off the excess acetone from the reaction mixture with acetoacetamide-N-sulfofluoride and bringing about cyclization by a treatment with bases at a pH of from 5 to 12. The oxathiazinone derivatives are used as sweeteners.

Abstract: The installation has a continuous conveyor belt that is borne by supporting cables and moved along guide cables from a loading station to an unloading station. The belt is guided over deflecting drums in the loading and the unloading station. A respective turning device is located downstream of the unloading station and upstream of the loading station, and fastened on supporting frames. The device turns the return strand of the belt. The guide is formed with a helically running guide track that turns the belt downstream of the unloading station and upstream of the loading station.

Abstract: 1476101 N-Fluorosulphonylacetoacetamide HOECHST AG 2 Oct 1975 [3 Oct 1974] 40314/75 Heading C2C N-Fluorosulphonylacetoacetamide is prepared by reacting sulphamoyl fluoride with diketene at 50-100 C., preferably in an inert solvent. It may be reacted with methanolic KOH to give 6-methyl-3,4-dihydro-1,2,3- oxathiazine-4-one-2,2-dioxide as the potassium salt.
