Abstract
The invention discloses a method for removing trichloroethyl of glucoside, which is characterized in that 2,2,2-trichloro-ethyl glycoside, Zn powder and ammonium chloride (NH4Cl) are dissolved in an organic solvent and are subject to the trichloroethyl removal reaction at the temperature of 15 to 120 DEG C, the molar volume ratio of the trichloro-ethyl glycoside, the Zn powder, the ammonium chloride (NH4Cl) and the organic solvent is 1mol:2 to 30 mol: 1 to 20 mol: 2 to 20 L, and the reaction product is filtered, decompressed and concentrated to obtain anomeric carbon-exposed sugar. Compared with the prior art, the trichloroethyl removal method has short reaction time, convenient post-treatment, high yield, wide application range, small toxicity of the raw material, environmental protection, economical performance and high efficiency, and has important significance on promoting the application of the -trichloro-ethyl glycoside in the carbohydrate chemistry and chemical engineering production.
