Abstract
A process for selectively deacetylating an acetyl derivative of a saccharide is described, comprising treating an acetyl derivative of a monosaccharide or oligosaccharide using a mixture of an aqueous solution of alkali metal hydroxide/aqueous hydrogen peroxide/organic solvent to selectively hydrolyze acetate bonds at specific positions in the molecule, and thereby obtain a partially hydrolyzed acetyl derivative of a saccharide.
