Abstract
A thermal analysis of a solution of acetohydroxamic acid in 12 mol/L HNO3 was carried out. The activation energy, the speci c thermal e ect, the duration and rate of the exothermic reaction, the pre-exponential factor, the onset temperature and self-heating value of the sample, and the change in pressure and the speci c volume of the evolved gases were determined. It was shown that under experimental conditions this reaction proceeds in the autocatalytic mode. On the basis of experimental data, a kinetic equation for the reaction was obtained, which was used to create a model of the reaction under various conditions. The reliability of the simulation results was veri ed by di erential scanning calorimetry.
