    摘要:

    通过K(FOX-7)·H2O和Cu(NO3)2·3H2O在1, 3-丙二胺溶液中的反应制得含能配合物Cu(pn)2(FOX-7)2 (pn=1, 3-丙二胺)。用差示扫描量热法(DSC)和热重/微商热重法(TG/DTG)研究了Cu(pn)2(FOX-7)2的热分解行为，采用微量热DSC法测定了比热容，也研究了绝热至爆时间和撞击感度。结果表明, 第一放热分解过程的非等温动力学方程为:dα/dT=(1017.83/β) 3α2/3exp(-1.635×105/RT)。自加速分解温度和热爆炸临界温度分别为145.6 ℃和146.74 ℃。298.15 K时摩尔比热容为653.79 J·mol-1·K-1。绝热至爆时间约为77 s，Cu(pn)2(FOX-7)2的特性落高(H50)是71 cm (>14 J)(RDX>7.5 J), Cu(pn)2(FOX-7)2是相对不敏感的。

    Abstract:

    The energetic complex [Cu(pn)2(FOX-7)2] (pn=1, 3-diaminopropane) was synthesized by the reaction of K(FOX-7)·H2O and Cu(NO3)2·3H2O in 1, 3-diaminopropane solution. The thermal decomposition behavior was studied by differential scanning calorimetry (DSC) and thermogravimetry/derivative thermogravimetry (TG/DTG), the specific heat capacity was determined with a micro-DSC and the adiabatic time-to-explosion and the impact sensitivity were studied as well. Results show that the non-isothermal decomposition kinetic equation of the first decomposition process is dα/dT=(1017.83/β)3α2/3exp(-1.635×105/RT). The self-accelerating decomposition temperature and critical temperature of t hermal explosion are 145.6 ℃ and 146.7 ℃, respectively. The molar heat capacity is 653.79 J·mol-1·K-1 at 298.15 K. Adiabatic time-to-explosion is about 77 s, and the characteristic drop height (H50) of Cu(pn)2(FOX-7)2 is 71 cm (>14 J) (RDX, >7.5 J), which indicating Cu(pn)2(FOX-7)2 is relatively less sensitive.
