Thermal behavior of 3,4,5-triamino-1,2,4-triazole dinitramide

Abatract. The enthalpies of dissolution for nitroguanidine (NQ) in dimethyl sulfoxide (DMSO) andN,N-dimethylformamide (DMF) were measured using a RD496-2000 Calvet microcalorimeter at 298.15 K. Empirical formula for the calculation of the enthalpies of dissolution (ΔdissH) was obtained from the experimental data of the dissolution processes of NQ in DMSO and DMF. The corresponding kinetic equations describing the dissolution processes were dα/dt=10-1.49(1-α)0.94for the dissolution of NQ in DMSO and dα/dt=10-1.59(1-α)0.90for the dissolution of NQ in DMF.

“…Recently, significant progress has been made in designing new and improved high energy density materials (HEDMs) that exhibit good performance. At the same time, thermal behavior studies of energetic materials have attracted considerable attention [9][10][11][12][13] because they are very important to the evaluation of the thermal property and safety of the materials and is particularly useful and important in the assessment of these materials for potential application as explosives.…”

New energetic bis (2,2-dinitroethyl-N-nitro) ethylenediamine-based salts exhibiting reasonable physical properties, good detonation properties and relatively low impact sensitivities were synthesized in high yield by direct neutralization reactions. The thermal decomposition behavior of two new bis (2,2-dinitroethyl-N-nitro) ethylenediamine-based energetic salts was firstly measured using differential scanning calorimetry (DSC) at six different heating rates. The thermal decomposition kinetics and several thermodynamic parameters of the salts, such as apparent activation energy (E), pre-exponential factor (A), extrapolated onset temperature (T0), activation entropy (∆S≠), activation enthalpy (∆H≠), activation Gibbs free energy (∆G≠), critical temperature of thermal explosion (Tb) and the Arrhenius equations were obtained under non-isothermal conditions by DSC.
