Thermal reactivities of 1,3,5-trinitroso-1,3,5-triazinane (TmTa), 1,3,5-trinitro-1,3,5-triazinane (RDX), 2,4,6-trinitrotoluene (TNT), TNT/TmTa and RDX/TmTa mixtures and mixtures of 1,3,5-trinitrobenzene (TNB) with TmTa and TMTA/RDX were specified by means of differential thermal analysis with outputs evaluation by the Kissinger method. The reactivities, expressed as Ea R-1 slopes of Kissinger relationship, correlate with squares of detonation velocities of the corresponding explosive samples in the sense of modified Evans-Polanyi-Semenov equation. Taking this fact it is stated that initiation of detonation of the mixtures with TMTA content proceeds through primarily fission of the TMTA molecule. If an ionic mechanism dominantly participates on thermal decomposition of some studied mixtures then resulting Ea R-1values do not correlate in the sense of the equation. This is the case of the TNT/TmTa mixtures where TNT has acidic character toward TmTa. also in TNB/TmTa/RDX mixture might react amine intermediates of TmTa thermal decomposition with RDX by ionic mechanism.
