| titleOfInvention | Improvements in or relating to the oxidation of cellulose |
| abstract | Oxycellulose is obtained by treating cellulose with a mixture of nitrogen dioxide and a chlorinated hydrocarbon. The nitrogen dioxide is employed in solution in the chlorinated hydrocarbon, the solution being obtained by mixing liquid nitrogen dioxide with or bubbling gaseous nitrogen dioxide through the liquid hydrocarbon. Specified chlorinated hydrocarbons are carbon tetrachloride, ethylene dichloride, propylene dichloride, hexachlorethane, tetrachlorethane and chlorobenzene. Cellulose in the form of loose cotton, gauze, paper sheet, threads or wood pulp may be oxidized. The reaction is effected by immersing the cellulose in the solution preferably at room temperature and alkali-soluble or alkali-insoluble oxycellulose is obtained according to the degree of oxidation required. Numerous examples are given in which cellulose is oxidized by immersion in a solution of nitrogen dioxide in carbon tetrachloride or propylene dichloride at room temperature. |
