Thermal decomposition property of BNCP

The thermal decomposition property of bis-(5-nitro-2H-tetrazolato-N ²) tetraamine cobalt (III) perchorate (BNCP) was investigated by DSC and compared with those of BTF and HNS-IV. The kinetic parameters of thermal decomposition of BNCP, BTF and HNS-IV were calculated by Kissinger's method and Ozawa's method. At 10°C/min BNCP has an exothermic peak on the DSC curve at 289.6°C, which is 25.4°C larger than that of BTF, BNCP has the largest decomposition enthalpy compared with BNCP and BTF. BNCP is thermally stable under 100°C, which is confirmed by VST and TG. The apparent activation energy of thermal decomposition of BNCP by Kissinger's method is 178.3kJ/mol, which is 46.4kJ/mol less than that of BTF and 43.1kJ/mol less than that of HNS-IV, and by Ozawa's method is 187.5kJ/mol, being less about 33.8kJ/mol and 32.8kJ/mol than those of BTF and HNS-IV.
