Polysaccharides are at least partially hydrolyzed by contact with a composition containing urea, sulfuric acid, and water in which the urea/sulfuric acid molar ratio is less than 2. Such proportions of urea and sulfuric acid assure the presence of the monourea adduct of sulfuric acid. The polysaccharide can be hydrolyzed to an extent sufficient only to hydrate the polysaccharide to produce a hydrated polysaccharide such as hydrated cellulose, or it can be completely hydrolyzed to its constituent monosaccharides. Thus, cellulose can be converted to glucose.
