摘要
利用DSC法研究了高氯酸[四氨.双(5-硝基四唑)]合钴(Ⅲ)(BNCP)的热分解性能,并与苯并三氧化呋咱(BTF)和超细六硝基茋(HNS-Ⅳ)的热分解性能进行了比较,用Kissinger法和Ozawa法得到了BNCP、BTF、HNS-Ⅳ热分解反应动力学参数。在10℃/min的升温速率下,BNCP的分解峰温为289.6℃,比BTF高25.4℃,其分解热焓在3者中最大。VST、TG研究表明,BNCP在100℃以下具有良好的热安定性。Kissinger法得到的BNCP分解表观活化能为178.3kJ/mol,比BTF和HNS-Ⅳ分别低46.4kJ/mol和43.1kJ/mol;而用Ozawa法得到的BNCP分解表观活化能为187.5kJ/mol,比BTF和HNS-Ⅳ分别低约33.8、32.8kJ/mol。
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℃/min BNCP has an exothermic peak on the DSC curve at 289. 6 ℃, which is 25.4℃ larger than that of BTF, BNCP has the largest decomposition enthalpy compared with BNCP and BTF. BNCP is thermally stable under 100 ℃, 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 43.1 kJ/mol less than that of HNS- Ⅳ , and by Ozawa＇s method is 187.5kJ/mol, being less about 33.8kJ/mol and 32.8 kJ/mol than those of BTF and HNS- Ⅳ.
