| titleOfInvention | Production of cellulose acetate |
| abstract | P.C.Leithem-R.J.Conca 1-5 PRODUCTION OF CELLULOSE ACETATE Abstract of the Disclosure Cellulose acetate is produced by subjecting highly purified cellulosic dissolving pulp to a bleaching sequence including at least one alkaline extraction stage and acetylating the bleached pulp to convert the pulp to cellulose acetate. The yellowness index of the cellulose acetate is reduced by carrying out the alkaline extraction stage in the presence of from 0.2 to 3.3%, based on dry pulp weight, of sodium or hydrogen peroxide. |
