    摘要:

    利用DSC和TG-DTG法研究了Cu(NH3)2(FOX-7)2的热分解行为。第一放热分解过程的非等温分解动力学方程为$\frac{{{\rm{d}}\alpha }}{{{\rm{d}}T}} = \frac{{{{10}^{15.12}}}}{\beta }4{\alpha ^{3/4}}\exp ( - 1.429 \times {10^5}/{RT})$。Cu(NH3)2(FOX-7)2的自加速分解温度和热爆炸临界温度分别为145.5 ℃和156.2 ℃。利用微量热法研究了Cu(NH3)2(FOX-7)2的比热容, 25 ℃时的摩尔热容为447.3 J·mol-1·K-1。同时估算了Cu(NH3)2(FOX-7)2的绝热至爆时间大约为9.5 s。Cu(NH3)2(FOX-7)2的热稳定性远低于母体化合物FOX-7。

    Abstract:

    For fully understanding the thermal properties of Cu-FOX-7 complexes [FOX-7=1,1-diamino-2,2-dinitroethylene], thermal decomposition behavior of Cu(NH3)2(FOX-7)2 was studied with DSC and TG-DTG methods. The kinetic equation of the first exothermic decomposition process is $\frac{{{\rm{d}}\alpha }}{{{\rm{d}}T}} = \frac{{{{10}^{15.12}}}}{\beta }4{\alpha ^{3/4}}\exp ( - 1.429 \times {10^5}/{RT})$. The self-accelerating decomposition temperature and critical temperature of thermal explosion are 145.5, 156.2 ℃, respectively. The thermal stability of Cu(NH3)2(FOX-7)2 is much lower than that of FOX-7. The specific heat capacity of Cu(NH3)2(FOX-7)2 was determined with a micro-DSC method. Molar heat capacity is 447.3 J·mol-1·K-1 at 25 ℃. Adiabatic time-to-explosion was also estimated to be about 9.5 s. The thermal stability of Cu(NH3)2(FOX-7)2 is much lower than that of (FOX-7).
