摘要
通过K(FOX-7)·H_2O和Cu(NO_3)_2·3H_2O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=(10^(17.83)/β)3α^(2/3)exp(-1.635×10~5/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(H_(50))是71 cm(>14 J)(RDX>7.5 J),Cu(pn)_2(FOX-7)_2是相对不敏感的。
The energetic complex [ Cu （ pn ） 2 （ FOX-7 ） 2 （ pn = 1 , 3-diaminopropane ） was synthesized by the reaction of K （ FOX-7 ） H20 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 decom- position process is dα/d T= （ 1017.83//3） 3α2/3 exp （ - 1. 635 × 105/RT）. The self-accelerating decomposition temperature and critical temperature of thermal explosion are 145.6 ℃ and 146.7 ℃, respectively. The molar heat capacity is 653.79 1 mol-1 K-1 at 298.15 K. Adiabatic time-to-explosion is about 77 s, and the characteristic drop height （Hs0） 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.
