    摘要:

    通过溶液共结晶法制得CL-20/TNT共晶炸药, 采用扫描电镜(SEM)和X射线单晶衍射对其形貌和结构进行了表征, 该晶体属于正交晶系, Pbca空间群, 晶胞参数: a=0.9735(2) nm, b=1.9912(6) nm, c=2.4695(6) nm, α=β=γ=90°, V=4.787 nm3, Z=8。采用差示扫描量热(DSC)法分析了共晶炸药的热分解,并测定了其撞击感度, 结果表明,CL-20/TNT共晶炸药在180~275 ℃间放热分解,并将TNT熔点显著提高50 ℃左右;共晶炸药撞击感度较低,并将CL-20撞击感度明显降低87%%。

    Abstract:

    A novel CL-20/TNT cocrystal explosive was prepared by cocrystallization in solution, and its morphology was characterized by scaning electron microscopy (SEM), and the crystal structure was determined using single crystal X-ray. Results show that the crystal is orthorhombic, space group Pbca with crystal parameters of a=0.9735(2) nm, b=1.9912(6) nm, c=2.4695(6) nm, α=β=γ=90°, V=4.787 nm3, Z=8. The thermal decomposition and impact sensitivity of the product were measured by differential scanning calorimetry (DSC) and sensitivity test, respectively. The results reveal that the exothermic decomposition of CL-20/TNT cocrystal explosive occurs in the temperature range of 180-275 ℃, and the melting point of TNT significantly increases by about 50 ℃. CL-20/TNT cocrystal has lower impact sensitivity and the impact sensitivity of CL-20 obviously reduces by 87%.
