Energetic performance of trinitromethyl nitrotriazole (TNMNT) and its energetic salts

Abstract

Little is known about trinitromethyl nitrotriazole (TNMNT) since the crystal structure, density, energetic performance, and thermal properties have not been determined. A detailed characterization of TNMNT and its hydrazinium and potassium salts and their potential as solid propellants and oxidizers has been established. TNMNT exhibits a high density (1.96 g cm⁻³) and positive enthalpy of formation (ΔH_f = +84.79 kJ mol⁻¹). TNMNT and its hydrazinium and potassium salts illustrate excellent detonation properties (P = 34.24 to 36.22 GPa, D = 8899 to 9031 ms⁻¹). TNMNT and its hydrazinium salt exhibit outstanding propulsive properties (I_sp = 247.28 to 271.19 s), and these are superior to AP (I_sp = 156.63 s) and ADN (I_sp = 202.14 s). The results suggest opening the door to utilizing TNMNT and its energetic salts in solid rocket propulsion.
