FIELD: chemistry.
SUBSTANCE: invention relates to production of hydroxyalkyl derivatives of polysaccharides. The method of producing 2,3-dihydroxypropyl chitosan involves reacting chitosan with glycidol in the presence of hydrochloric acid with ratio glycidol:chitosan:hydrochloric acid = (2-6):1:1, at room temperature until a gel forms. The mixture is then heated at 55-65°C for 12-14 hours and the reaction mass is treated with water. The mixture is then deposited, subjected to hot extraction with water-soluble alcohols or ketones and dried.
EFFECT: invention simplifies the method of production and output of the end product and improves sorption properties of the compound.
