Starch modifications with hypochlorite

Oxidative modification of starches with hypochlorite or peroxide 5delds dextrin-like substances which are used as adhesives. The reaction is complex, some depolymerization takes place, and carboxyl groups are formed. 

Starch oxidation was investigated as early as 1829 by Liebig. The objective, as with other modifications, was to obtain a modified granular starch. The oxidant commonly employed is sodium hypochlorite, prepared from chlorine and aqueous sodium hydroxide. This reaction is exothermic and external cooling must be provided during preparation of the oxidant.
