Synthesis and characteristics of novel energetic salts based on bis(N-dinitroethyl)aminofurazan

Abstract

Energetic salts based on bis(N-dinitroethyl)aminofurazan were synthesised. All salts were fully characterised using ¹H and ¹³C multinuclear NMR spectroscopy, infrared spectroscopy, elemental analysis, density analysis, and differential scanning calorimetry. These salts exhibited reasonable physical properties, such as high densities (1.72 g cm⁻³ to 1.94 g cm⁻³) and low solubilities in water. Based on the experimental densities, the detonation pressures and velocities of the energetic salts were calculated, ranging from 26.1 GPa to 39.4 GPa and 8055 m s⁻¹ to 9388 m s⁻¹, respectively. These value were higher than those of TNT and similar to those of RDX. The thermal stability and thermal kinetic parameters of the new energetic salts were also evaluated using Kissinger’s and Ozawa’s methods, coupled with DSC.
