Abstract
Two environmentally friendly energetic salts (en)(PA)2·2H2O (1) and (pn)(PA)2·H2O (2) (en=ethylenediamine, pn=1, 3-diaminopropane and PA=picrate) were synthesized and characterized by elemental analysis and FT-IR spectroscopy. The crystal structures were determined by X-ray single crystal diffraction. The results show that they belong to the orthorhombic space group Pnma. Thermal decomposition mechanisms were investigated through differential scanning calorimetry (DSC) and thermo-gravimetric analysis (TGA). The non-isothermal kinetics parameters were also studied by applying the Kissinger and Ozawa's methods. In addition, the experimental data showed that the energies of combustion of 1 and 2 were slightly higher than to the energies of combustion of RDX (1, 3, 5-trinitro-1, 3, 5-triaza-cyclohexane) and HMX (1, 3, 5, 7-tetranitro-1, 3, 5, 7-tetraazocane). Determination of the sensitivities revealed lower sensitivities as compared to KPA (potassium picrate).
