英文摘要: An energetic cocrystal containing benzotrifuroxan (BTF) and 1,3-dinitrobenzene (DNB) in 1:1 molar ratio was prepared by slow evaporation of solvent. The structure of the cocrystal was determined by single crystal X-ray diffraction (XRD). It belongs to the monoclinic crystal system with space group P2(1)/c. The performance of the cocrystal was evaluated on the basis of thermolysis, impact sensitivity, and detonation properties. Differential scanning calorimetry (DSC) revealed that the cocrystal has a melting point of 130 degrees C, which is an increase of 38 degrees C compared to pure DNB; the decomposition temperature is similar to that of pure BTF. The cocrystal exhibits an impact height with 50% ignition probability of 88cm, suggesting a substantial reduction in impact sensitivity compared to pure BTF. Furthermore, the cocrystal is predicted to have a detonation velocity of about 7373ms(-1) and a detonation pressure of about 24GPa, respectively, indicating excellent detonation performance.
