| titleOfInvention | Process for producing oxathiazines |
| abstract | (57) [Summary] [PROBLEMS] To obtain oxathiazines of high purity. SOLUTION: The method of the present invention is obtained by cyclizing a sulfonic acid represented by the following formula (1a), and converting the oxathiazine (1) from a reaction mixture containing the oxathiazine represented by the following formula (1). A) separating the oxathiazines (1) into a second aqueous layer by adding water to the separated organic layer, and distributing the oxathiazines (1) to a second aqueous layer. And extracting the oxathiazines (1) from the aqueous layer with an organic solvent. Embedded image (Wherein, R 1 and R 2 are the same or different and each represent a hydrogen atom or an organic group; R 3 represents a hydrogen atom, an organic group, or an inorganic metal atom which forms a salt by bonding to a nitrogen atom; Represents a base that forms a salt with a hydrogen atom or a sulfonate group) |
