Abstract: THINNING OF DERIVATIZED STARCH IS ACCOMPLISHED WITH THE USE OF HYDROGEN PEROXIDE UNDER ALKALINE CONDITIONS REQUIRED FOR THE DERIVATIZATION. THE TEMPERATURE AT WHICH THINING OF DERIVATIZED STARCHES IS ACCOMPLISHED WITH THE USE OF HYDROGEN PEROXIDE IS IN THE RANGE OF 80* TO 130*F. AND AT A PH IN THE RANGE OF 7.0 TO 12.0. A CATALYTIC MATERIAL SUCH AS COPPER ION IS USED IN THE AMOUNT OF 5 PARTS TO 100 PARTS PER MILLION BASED ON THE WEIGHT OF STARCH TO ASSIST THE THINNING ACTION OFTHE HYDROGEN PEROXIDE.
