Oxidation of cotton cellulose with potassium dichromate–sulfuric acid, potassium permanganate, and sodium hypochlorite in the presence and absence of chelating agents (ethylenediamineteteraacetic acid and nitrilotriacetic acid) at 30°C (for 1, 2, and 3 hr) has been studied with respect to the extent of decomposition of the oxidant on the one hand and the changes in the copper number, carboxyl value, and cuprammonium fluidity of cellulose on the other. The effects of chlorous acid and sodium borohydride treatments on these properties have also been studied. Chelating agents are shown to protect cellulose during the oxidation, and EDTA is more effective in this respect.
