“…It is noted that the C 1 -N 1 BDE is the biggest for compound (5) and equal to 68.2 kcal/mol, which is much bigger than those of the C 3 -N 3 and C 4 -N 4 bonds, the C 4 -N 4 BDE is the smallest. For compound (6), the BDEs of the C 3 -N 3 and Table 1 Bond dissociation energies (BDE, kcal/mol) for seven title compounds at B3LYP/6-31G* and B3P86/6-31G* levels Compound B3LYP/6-31G* B3P86/6-31G* H 50 Numbers in bold mean that the corresponding bond is most reactive in the studied compound C 5 -N 5 bonds are equivalent, and their BDEs are all equal to 63.9 kcal/mol. The C 1 -N 1 BDE is the biggest and equal to 68.1 kcal/mol, which means that the C 3 -N 3 bond should be initial scission step.…”

Based on the full-optimized molecular geometric structures at B3LYP/6-31G* and B3P86/6-31G* levels, the densities (q), detonation velocities (D), and pressures (P) for a series of 1,2,3-triazole derivatives, as well as their thermal stabilities, were investigated to look for high energy density compounds (HEDCs). The heats of formation (HOFs) are also calculated via designed isodesmic reactions. The calculations on the bond dissociation energies (BDEs) indicate that the BDEs of the initial scission step are between 53 and 70 kcal/mol, and 4-nitro-1,2,3-triazole is the most reactive compound, while 1-(2 0 ,4 0 -dinitrophenyl)-5-nitro-1,2,3-triazole is the least reactive compound for 1,2,3-triazole derivatives studied. The condensed phase heats of formation are also calculated for the title compounds. These results would provide basic information for the further studies of HEDCs. The detonation data of 1-(3 0 ,4 0 -dinitrophenyl)-4-nitro-1,2,3-triazole and 1-(2 0 ,4 0 -dinitrophenyl)-4-nitro-1,2,3-triazole show that they meet the requirement for HEDCs.

“…4-Amino-5-nitro-1,2,3-triazole (ANTZ), recently being identified as a kind of potential high performance insensitive explosive, [1][2][3][4][5][6] has some desirable attributes, including a high nitrogen content of 54%, high density 1.837 g•cm -3 (at 25 ℃ with measuring method of 401.1, GJB772A-97), combustion heat of 1350.501 kJ•mol -1 and relatively low sensitivity to shock or impact-included ignition with H 50 of 154 cm [with drop-weight of 10 kg and measuring method of 601.2, GJB772A-97, while that of cyclotetramethylenetetranitroamine (HMX) is 32 cm under the same measuring condition], which can be used as a main insensitive energetic component of cast explosives and propellants [7][8][9] in order to substitute 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), cyclotrimethylenetrinitramine (RDX) or HMX. There are several reports on the synthesis methods, characterization and the detonation properties of ANTZ, whose detonation velocity is 8909.403 m•s -1 and detonation pressure 35.657 GPa, 10,11 but there is no report about the derivatives of ATNZ.…”

4-Amino-5-nitro-1,2,3-triazole (ANTZ) and its derivatives, such as 2-(4-amino-5-nitro-1,2,3-trazole-1-yl)-1,3,5-trinitrobenzene (T-ANTZ) and 4-amino-5-nitro-1,2,3-triazole (M-ANTZ), were synthesized and characterized, whose structures were confirmed by IR, NMR and elemental analysis. The thermal behaviors of ANTZ, T-ANTZ and M-ANTZ were studied by the methods of DSC and TG-DTG, and the results showed that there is an obvious melting process of ANTZ with melting point of 278.38 ℃, while there is no melting process in the thermal behavior of T-ANTZ and M-ANTZ (the derivatives of ATNZ).
