PROCESS FOR PRODUCTION OF POLYSACCHARIDE AND/OR MONOSACCHARIDE BY HYDROLYSIS OF DIFFERENT POLYSACCHARIDE

摘要

THE OBJECT IS TO PRODUCE A POLYSACCHARIDE AND/OR A MONOSACCHARIDE EFFICIENTLY BY HYDROLYZING A DIFFERENT POLYSACCHARIDE EFFICIENTLY. THE HYDROLYSIS OF A POLYSACCHARIDE IS AN IMPORTANT MEANS FOR PRODUCING A MONOSACCHARIDE THAT CAN BE USED AS A STARTING MATERIAL FOR THE PRODUCTION OF ETHANOL, THE SOLUBILIZATION OF A WATER-INSOLUBLE POLYSACCHARIDE, AND THE PRODUCTION OF A USEFUL WATER-SOLUBLE LOW-POLYMERIC SACCHARIDE OR THE LIKE. FOR ACHIEVING THE OBJECT, A POLYSACCHARIDE TO BE HYDROLYZED IS REACTED WITH WATER IN THE PRESENCE OF A CARBONACEOUS MATERIAL HAVING SULFONIC ACID GROUP THEREIN TO CAUSE THE HYDROLYSIS OF THE POLYSACCHARIDE TO BE HYDROLYZED, THEREBY PRODUCING A OTHER POLYSACCHARIDE AND/OR A MONOSACCHARIDE.
