Two environmentally friendly energetic salts (en)(PA)2·2H2O and (pn)(PA)2·H2O based on ethylenediamine (en),1,3-diaminopropane (pn) and picrate (PA)
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-1R 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 thermogravimetric analysis (TGA).The non-isothermal kinetics parameters were also studied by applying the Kissinger and Ozawas 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 (l,3,5-trinitro-l,3,5-triaza-cyclohexane) and HMX (1,3,5,7-tetranitro-l,3,5,7-tetraazocane).Determination of the sensitivities revealed lower sensitivities as compared to KPA (potassium picrate).
