“…Kinetic parameters for TNM melt fall on the linear fit of data for trinitroethylnitroamino-based compounds. Kinetic data for TNM in solution also agree with the common line with the slight deviation for Freon, where the reaction between TNM and solvent is supposed . Thus, the obtained data for 1 – 3 kinetic parameters fully agree with the primary reaction of the C–NO 2 bond homolytic cleavage.…”

“…Kinetic data for TNM in solution also agree with the common line with the slight deviation for Freon, where the reaction between TNM and solvent is supposed. 62 Thus, the obtained data for 1−3 kinetic parameters fully agree with the primary reaction of the C−NO 2 bond homolytic cleavage. The activation energy of this process decreases from 141 kJ mol −1 for 1 to 121−122 kJ mol −1 for 2 and 3 due to the supposed lowering of the C−N bond strength.…”

Thermal decomposition of 1,3,5-triazines with azido, trinitroethyl, and nitramino groups, the three important energetic functionalities, has been studied with a range of thermal analysis tools. The involved compounds melt under heating with the following mass loss and heat and gas release in the course of thermal decomposition. Model-fitting kinetic analysis resulted in formal reaction schemes with two general stages. In case of the least energetic 6-azido-2,4-bis(2,2,2-trinitroethylamino)-1,3,5-triazine, the first reaction is a first-order reaction followed by a thirdorder reaction. Alternatively, for 6-azido-2,4-bis(2,2,2-trinitroethylnitramino)-1,3,5-triazine and 2,4,6-tris(2,2,2-trinitroethylnitramino)-1,3,5-triazine, the first step comprises the autocatalytic reaction. The activation energy for the first decomposition step drops from 141 to 122 kJ mol −1 due to the inductive influence of a β-nitramino group. The second general reaction for all species obeys the third-order reaction model with activation energies in the range 112−126 kJ mol −1 . On the basis of the analysis of the kinetic data and temporal behavior of the evolved gases, a similar primary decomposition channel, the homolytic cleavage of a C− NO 2 bond, has been proposed for all investigated substances.

The negative and positive ion mass spectra of a series of substituted trinitroalkanes (nitroform, tetranitro methane, methyl, fluoro, chloro, bromo and iodo-trinitro methane) have been measured with an Atlas CH-4 Mass Spectrometer, under varying electron energies from 70 eV over the total range at which ions are produced. The modes of decompostion of the compounds are presented. A few metastable transitions are observable in the negative ion spectra, but only at high electron energies (ion pair region) and are very low in intensity. The negative and positive ion clastograms of these polynitro compounds showed little parent-daughter ion correlation.Finally, the negative ions formed appear to contain excess amounts of kinetic energy even at low electron energies; as a result there is a great deal of overlap in the various mechanisms for the formation of negative ions.
