| Abstract: | The thermal behavior and kinetic parameters of the exothermic decomposition reaction of N‐methyl‐N‐nitro‐2,2,2‐trinitroethanamine in a temperature‐programmed mode have been investigated by means of differential scanning calorimetry (DSC). The kinetic equation of the exothermic decomposition process of the compound is proposed. The values of the apparent activation energy (Ea), pre‐exponential factor (A), entropy of activation (ΔS≠), enthalpy of activation (ΔH≠), and free energy of activation (ΔG≠) of this reaction and the critical temperature of thermal explosion of the compound are reported. Information is obtained on the mechanism of the initial stage of the thermal decomposition of the compound. |
