Crystal Structure and Catalytic Properties of an Energetic Complex Zn_4(C_4N_6O_5H_2)_4(DMSO)_4

以ANPyO、Zn(CH_3COO)_2·2H_2O和DMSO作原料,通过溶液法合成了含能配合物Zn_4(C_4N_6O_5H_2)_4(DMSO)_4,采用傅立叶变换红外光谱、元素分析、X-射线单晶衍射、差示扫描量热法(DSC)和热重分析法(TG)对其结构进行了表征,用Kissinger和Ozawa法计算了配合物放热过程的表观活化能。研究了配合物对黑索今(RDX)、奥克托今(HMX)和高氯酸铵(AP)热分解的催化效果,测试了其撞击感度和摩擦感度。结果表明,配合物属单斜晶系,空间群为P2_1/C。配合物热分解过程有一个吸热峰和一个放热峰,剩余残渣质量分数为14.38%;表观活化能为225.56 kJ/mol;配合物对RDX和HMX热分解催化效果不明显,但对AP具有非常显著的催化效果;配合物对撞击和摩擦钝感。

An energetic complex Zn4 （C4N6O5 H2）4 （DMSO）4 was synthesized by solution method using ANPyO, Zn（CH3COO）2 · 2H2O and DMSO as raw materials and structurally characterized by FT-IR spectroscopy, elemental analysis, X-ray single crystal diffraction, differential scanning calorimetry （DSC） and thermogravimetry （TG）. The apparent activation energy of exothermic process of the complex was calculated by Kissinger＇s method and Ozawa＇s method. The catalytic effect of the complex on the thermal decomposition of 1,3,5-trinitrohexahydro-1,3,5-triazine （RDX）, octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine （HMX） and ammonium perchlorate （AP） was explored. Its impact sensitivity and friction sensitivity were tested. Results show that the crystal of the complex belongs to the monoclinic system, space group P21/C. Thermal decomposition process of the complex has one endothermic peak and one exothermic peak with final residue amount of 14.38%. The value of apparent activation energy is de- termined to be 225.56 kJ · mol^-1. The complex has little catalytic effects on the thermal decomposition of RDX and HMX, but good catalytic effect to the thermal decomposition of AP. The complex is insensitive to impact and friction.
