Latest Patents

One of his latest patents involves a process for the preparation of acetoacetamide-N-sulfonic acid and its salts, which are cyclized with approximately equimolar amounts of SO.sub.3. This process results in the formation of 6-methyl-3,4-dihydro-1,2,3-oxathiazin-4-one 2,2-dioxide. When more than the equimolar amount of SO.sub.3 is used, the compound is produced as an SO.sub.3 adduct that requires hydrolysis. The hydrolysis occurs quickly and efficiently in specialized apparatus. The non-toxic salts, particularly the potassium salt of 6-methyl-3,4-dihydro-1,2,3-oxathiazin-4-one 2,2-dioxide, are recognized as valuable synthetic sweeteners.

Another patent details the preparation of 6-methyl-3,4-dihydro-1,2,3-oxathiazin-4-one 2,2-dioxide through the cyclization of acetoacetamide-N-sulfonic acid or its salts. This process utilizes an inert organic solvent and, if necessary, an inert inorganic solvent. The method includes steps for working up the reaction by adding aqueous sulfuric acid and purifying the resulting compound through crystallization.
