| titleOfInvention | Process for obtaining chlorinated sugar derivatives |
| abstract | The invention relates to the field of sugar chemistry, specifically to an improved method for producing chlorinated sugar derivatives selected from the group consisting of sucralose pentaacetate, sucralose 6-acetate, tetrachlorrafinose and 4,6,1 ′, 6′-tetrachloro-4,6,1 ′ , 6′-tetradeoxysaccharose. The method involves reacting a sugar derivative with thionyl chloride in the presence of a quaternary ammonium salt of the general formula N + R1R2R3R4CI-, R4 is a benzyl group. The amount of the quaternary ammonium salt is about 0.2-0.4 bq relative to the sugar or sugar derivative. Thionyl chloride is taken in excess from small to moderate, or in a 10% excess. |
