Decomposition of some polynitro arenes initiated by heat and shock

Decomposition of some polynitro arenes initiated by heat and shock

“…Attention was given to the initiation by heat, shock, and also to the residua of detonation of TNT charge. It was found that the main identified decomposition intermediates are identical in all the three cases [1]. It was stated that this finding excellently corresponds to the experimental results obtained by Bulusu et al [2,3] from the study of the TNT initiation by means of deuterium kinetic isotope effect (DKIE).…”

“…The exposition of samples of explosives to a shock wave was realized by means of the small-scale gap test [1,16] and with the donor charges (pentaerythritol tetranitrate, i.e. PETN, with 10 wt.% wax, and 1,3,5-trinitro-1,3,5-triazinane, i.e.…”

“…The intermediates of initiation of 2,4,6-trinitrotoluene (TNT) were dealt with in the first part [1] of this series. Attention was given to the initiation by heat, shock, and also to the residua of detonation of TNT charge.…”

“…The primary fission should concern the N OH bond homolysis in the molecule of its aci-form (so called "trinitrotoluene mechanism"-for general scheme see Ref. [1]) [4][5][6]. Polyamino derivatives of 1,3,5-trinitrobenzene fall into the same category of compounds, too.…”

Liquid state thermochemical decomposition of neat 1,3,5,5-tetranitrohexahydropyrimidine (DNNC) and its DNNC-d2, DNNC-d4, DNNC-d6 structural isotopomers: Mechanistic entrance into the DNNC molecule

“…Literature precedence also suggests that the skeletal ring structure of cyclic energetic materials is attacked late during the thermochemical decomposition process after the rate-controlling bond rupture occurs [2,3,5,[8][9][10]12,24,25,28,29,41,42,45,46]. Therefore, the consistent decrease in DNNC decomposition rate with increased deuterium substitution in Table 7 cannot be a random occurrence under these documented mechanistic circumstances.…”
