Technical Abstract: Thermochemical oxidation of starches of different amylose content (0-70%) 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 self-induced exothermal initiation- drum drying, jet cooking-drum drying, and drum drying using hydrogen peroxide and a ferrous-cupric catalyst. Data will be presented to show product preparation, properties, and analysis. Preliminary data will be presented for end-use applications in the areas of: 1) sequestration of calcium, manganese, and iron and 2) extenders in phenol-formaldehyde adhesives for plywood. Other potential applications being researched are set retardation and water reduction in concrete admixes, builders for detergents, micronutrient chelators, textile sizers, metal and rust cleaners, and cotton mercerizers.
