Interpretive Summary:

Technical Abstract: Thermochemical oxidation of starches of different amylose content was investigated to maximize carboxyl and carbonyl content, to increase water solubility and to give products with new and novel properties. Thermochemical processes evaluated were jet cooking-drum drying, extrusion-drum drying and drum drying. Oxidants evaluated were hypochlorite and hydrogen peroxide. Use of ferrous-cupric catalyst and hydrogen peroxide offered optimal properties. Data will be presented to show product properties and analysis. Preliminary data will be presented for end-use applications in the areas of: 1) sequestration of calcium, manganese and iron; 2) set retardation and water reduction in concrete admixes; 3) extenders in phenol-formaldehyde adhesives for plywood and 4) builders for detergents. Other potential applications being researched are micronutrient chelators, textile sizers, metal and rust cleaners and cotton mercerizers.
