Abstract

Three high-energy salts (3, 4 and 5) based on oxy-bridged bis(gem-dinitro) furazan with potassium and nitrogen-rich cations were reported. Their structures were fully characterized and confirmed by NMR (¹H, ¹³C), IR spectroscopy, elemental analysis and single crystal X-ray diffraction. The thermal decomposition behaviors were studied by DSC and TG methods. And, the decomposition process of 5 was studied by the thermolysis in-situ rapid-scan FTIR. The non-isothermal kinetics parameters were obtained by Kissinger's and Ozawa's methods, respectively. The activation entropy (ΔS^≠), activation enthalpy (ΔH^≠), activation Gibbs free energy (ΔG^≠) and the critical temperature of thermal explosion were calculated.
