Oxidation of carbohydrates
Abstract
Abstract CARBOHYDRATES SUCH AS STARCH AND CELLULOSE HAVING UNSUBSTITUTED PRIMARY HYDROXYL GROUPS ARE OXIDIZED WITH AN ALKALI METAL FERRATE, SUCH AS POTASSIUM FERRATE, TO YIELD PRODUCTS IN WHICH AT LEAST ONE OF THE PRIMARY HYDROXYL GROUPS IS CONVERTED TO AN ALDEHYDE GROUP. THE USE OF SUCH A FERRATE COMPOUND AS THE OXIDIZING AGENT PERMITS OXIDATION TO BE CARRIED OUT WITHOUT THE FORMATION OF CARBOXYL GROUPS, WITHOUT THE OXIDATION OF SECONDARY HYDROXYL GROUPS AND WITHOUT SCISSION OF CARBON TO CARBON BONDS IN THE CARBOHYDRATE MOLECULES. THE RESULTING PRODUCTS EXHIBIT IMPROVED PHYSICAL PROPERTIES AND MAY BE USED, FOR EXAMPLE, IN PAPER SIZING APPLICANTS OR AS CHEMICAL INTERMEDIATES IN THE PREPARATION OF OTHER USEFUL DERIVATIVES.
