Effect of Uranyl Nitrate on Exothermic Processes in Nitric Acid Solutions of Reductants
The thermal stability of nitric acid solutions of acetohydroxamic acid, carbohydrazide, hydrazine nitrate, and their mixtures was studied. The onset temperature of the exothermic reaction was determined, and the thermal effects of the reactions were calculated. The effect of uranyl nitrate on the thermal stability of reducing agents and their mixtures was studied. Comparison of the characteristics of exothermic processes in solutions with and without uranyl nitrate showed that the introduction of uranyl nitrate reduced the intensity of exothermic processes in all the nitric acid solutions studied.
