Bis(2,2-dinitroethyl-N-nitro)ethylenediamine-Based Energetic Salts and Their Thermolysis Studies

摘要

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 (T_0), activation entropy (ΔS~≠), activation enthalpy (ΔH~≠), activation Gibbs free energy (ΔG~≠), critical temperature of thermal explosion (T_b) and the Arrhenius equations were obtained under non-isothermal conditions by DSC.
