Abstract

Three kinds of energetic complexes, Co (CHZ)₄(PA)₂ · 3H₂O, Cu (CHZ)₄(PA)₂ · 4H ₂O and Pb (CHZ)₂ (PA)₂ · 4H₂O (CHZ= carbodihydrazide, PA= picric acid), were synthesized with carbohydrazide, picric acid and corresponding metallic (Co, Cu, Pb) salts. The molecular formulas of these coordination compounds were derived by using elemental analyses and FT-IR techniques. The friction, impact and flame sensitivities of the complexes were tested followed by the standard methods. The effects of the energetic complexes on the thermal decomposition of CL-20 were studied by means of DSC and TG-DTG techniques. The results show that the addition of those complexes make the onset temperature and peak temperature of CL-20 shift to low temperature. The kinetic parameters E_a and A of the first exothermic decomposition process for complexes/CL-20 mixture were calculated by Kissinger's method and Ozawa-Doylés method. Cu (CHZ)(PA) and (CHZ)(PA) make the E_a value of the exothermic processes of CL-20 decrease from 222.8 kJ/mol to 186.6 kJ/mol and 183.0 kJ/mol.
