Abstract

A series of dialdehyde glucans (obtained from starch, amylose, amylopectin, maltodextrin, cellulose, and dextran by periodate glycol cleavage) were oxidized to the corresponding dicarboxy polysaccharides by the combined use of NaClO3 and H2O2 (two moles of each per mol dialdehyde moieties). As compared to the conventional method (using 6 mol of chlorite and no peroxide), this new procedure reduced oxidant costs by a factor of 2.5, avoided the evolution of toxic ClO2, and more selectively yielded dicarboxy polysaccharides of high mol. wt. with excellent Ca complexing properties. The products thus obtained were potentially attractive co-builders in phosphate-free detergents.
