METHOD OF CARBOHYDRATE SILYLATION Russian patent published in 1996 - IPC

FIELD: chemical technology. SUBSTANCE: carbohydrates were converted in autoclave at temperature about 0 C to 200 C with silylating agent of the formula (I) in liquid nitrogen compound of the formula (II) . In both formulas the corresponding residues mean independently R₁R₂R₃R₁₀ - H; R₄R₅R₆R₇R₈R₉=CH₃. Hexamethylsilazane is the most suitable silylating agent and ammonia is used as an liquid nitrogen compound mainly. EFFECT: enhanced purity of products, decreased cost. 1 tbl
