A method of hydrolyzing cellulose to monosaccharides, especially glucose, by subjecting cellulose, under controlled temperature and pressure, to an aqueous mixture of calcium chloride and an acid, preferably hydrochloric acid, providing a low concentration of H<+>. When the starting material is pure alpha cellulose, glucose is produced in very high yields. When the starting material is a mixture of hemi and alpha cellulose, the resultant product is a mixture of pentose (xylose) and hexose (glucose) sugars. Refluxing the reaction mixture containing pure alpha cellulose, about 55% calcium chloride and only about 0.01% hydrochloric acid, based on the total reaction mass, will produce in a relatively short time relatively high yields of glucose.
