Аннотация:A thermal analysis of an acetohydroxamic acid solution in 12 M HNO3 was carried out. The activation energy, specific thermal effect, time and rate of the exothermic reaction, pre-exponential factor, starting temperature and self-heating value of the sample, pressure change and specific volume of released gases were determined. Under experimental conditions this reaction was found to occur in an autocatalytic mode. Based on experimental data, a kinetic equation for the reaction was derived, which was used to create a model of the reaction under various conditions. The reliability of the modeling results was verified by differential scanning calorimetry.
