摘要
采用溶剂挥发方式制备出苯并三氧化呋咱(BTF)和2,4-二硝基苯甲醚(DNAN)以2∶1(摩尔比)结合形成的新型共晶炸药。BTF-DNAN共晶的结构通过单晶衍射表征,同时研究了共晶撞击感度。结果表明,BTF-DNAN共晶属于单斜晶系,P21/c空间群。共晶的撞击感度特性落高H_(50)大于112 cm,较单组分BTF,显著降低了撞击感度。
A novel cocrystal explosive composed of benzotrifuroxan （BTF） and 2,4-dinitroanisole （DNAN） in a 2 ： 1 molar ratio was prepared by an evaporation solvent method, its structure was characterized by the single crystal X-ray diffraction （SXRD） and the impact sensitivity was studied as well. Results show that the cocrystal explosive belongs to monoclinic system with P21/c space group. The cocrystal displays an Hs0 of above 112 cm, indicating lower sensitivity compared to pure BTF.
