Abstract

1330123 Oxidation of polysaccharides UNILEVER Ltd 20 Aug 1970 6379/73 Divided out of 1330121 Heading C3U A process for oxidizing polysaccharides to form oxidized polysaccharides (e.g. starch or cellulose) having at least 20% of dicarboxyl units per 100 anhydroglucose units of the original polysaccharide comprises contacting the polysaccharide with sodium hypochlorite at a pH of from 8 to 8À5, preferably 8À25.
