“…5,6 Previously, we described the room temperature isotherm and compressibility of monoclinic TNT, and observed a solid-solid phase transition near 23 GPa, which was irreversible upon decompression. 7,8 There has also been limited experimental evidence of an ambient-pressure phase transition at 337-338 K marked by dilatometric expansion, 9 and subtle pressure-induced changes to vibrational spectra at $2 GPa and 298 K suggested structural modifications to the parent monoclinic phase. 10 The chemical stability of molten TNT at ambient pressure has been studied previously by Brill and James 11 and Beckman et al 12 TNT's low T M arises from its weak intermolecular interactions, and low crystal symmetries.…”

2,4,6-trinitrotoluene (TNT) is a molecular explosive that exhibits chemical stability in the molten phase at ambient pressure. A combination of visual, spectroscopic, and structural (x-ray diffraction) methods coupled to high pressure, resistively heated diamond anvil cells was used to determine the melt and decomposition boundaries to >15 GPa. The chemical stability of molten TNT was found to be limited, existing in a small domain of pressure-temperature conditions below 2 GPa. Decomposition dominates the phase diagram at high temperatures beyond 6 GPa. From the calculated bulk temperature rise, we conclude that it is unlikely that TNT melts on its principal Hugoniot.

“…(1.36 × 10 –4 K –1 at 300 K). Over the temperature range 323–337 K, Rosen et al report α to be 3.03 × 10 –4 K –1 . Based on these results, we assume that α varies linearly from the value obtained by Vrcelj et al at 293 K to that reported by Rosen et al at 330 K, which is the midpoint of the temperature range in their study.…”

“…Vrcelj et al 41 have found α at room temperature (293 K) for the more stable (i.e., monoclinic) form of TNT to be 2.06 × 10 −4 K −1 , which agrees with the α measured by Heberlein 42 but is higher than the values reported by Dobratz and Crawford 36 (1.8 × 10 −4 K −1 ) and Sorescu et al 43 (1.36 × 10 −4 K −1 at 300 K). Over the temperature range 323−337 K, Rosen et al 44 report α to be 3.03 × 10 −4 K −1 . Based on these results, we assume that α varies linearly from the value obtained by Vrcelj et al at 293 K to that reported by Rosen et al at 330 K, which is the midpoint of the temperature range in their study.…”

Energetic materials are substances that can undergo rapid, exothermic reactions when subjected to an external stimulus, such as heating. In this work, we show that the well-known Peng−Robinson equation of state can be applied to energetic materials, whether they are pure components, liquid mixtures, or solid mixtures. We are specifically interested in two energetic materials: hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and 2,4,6-trinitrotoluene (TNT). We model RDX and TNT in both their liquid and solid phases, as well liquid and solid mixtures of the two compounds. Our work examines temperatures and pressures as high as about 500 K and 2500 bar, respectively. The Peng−Robinson equation of state provides a good representation of experimental volumetric (e.g., density and bulk modulus), thermal (heat capacity), and phase behavior (melting temperature and solubility) data. It can be applied to other energetic materialsranging in complexity from pure components to multiphase, multicomponent mixturesby adapting the procedures described in this study.

We describe the construction of a complete equation of state for the high explosive Composition B in its unreacted (inert) form, as well as chemical equilibrium calculations of its detonation products. The multiphase reactant EOS is of SESAME type, and was calibrated to ambient thermal and mechanical data, the shock initiation experiments of Dattelbaum, et al., and the melt line of trinitrotoluene (TNT).
