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 performance of perchlorate (tetrakisammonium bis (5-nitrotetrazolato) cobalt (Ⅲ)) (BNCP) was studied by DSC. The thermal decomposition performance of BNCP was compared with that of benzofurans (BTF) The thermal decomposition properties of HNS-Ⅳ were compared. The thermal decomposition kinetic parameters of BNCP, BTF and HNS-Ⅳ were obtained by Kissinger method and Ozawa method. At a heating rate of 10 ℃ / min, the decomposition peak temperature of BNCP was 289.6 ℃, which was 25.4 ℃ higher than that of BTF. The decomposition enthalpy of BNCP was the highest among the three. VST, TG studies have shown that BNCP has good thermal stability below 100 ℃. The apparent activation energy of BNCP decomposition obtained by Kissinger method was 178.3 kJ / mol, which was 46.4 kJ / mol and 43.1 kJ / mol lower than that of BTF and HNS-IV, respectively. The apparent activation energy of BNCP decomposition by Ozawa method was 187.5 kJ / mol, about 33.8 and 32.8 kJ / mol lower than that of BTF and HNS-IV, respectively.
