摘要
以1,5⁃环辛二烯为原料,经氧化环合、O⁃酰化、消除、环氧化、氨解和硝化等步骤,合成了一种新型笼状含能化合物6⁃硝基⁃2⁃氧杂⁃6⁃氮杂金刚烷⁃4,8⁃二醇二硝酸酯。利用X射线单晶衍射技术获得了6⁃硝基⁃2⁃氧杂⁃6⁃氮杂金刚烷⁃4,8⁃二醇二硝酸酯的单晶结构;采用核磁、红外以及元素分析对其结构进行了表征;采用热重分析(TG)和差示扫描量热法(DSC)研究了目标化合物的热稳定性;经密度泛函理论研究了目标化合物的爆轰性能。结果表明,其密度为1.75 g·cm^(-3),热分解放热峰值为184℃,爆速7730 m·s^(-1),爆压为26.07 GPa。
A novel cage⁃like energetic compound,6⁃nitro⁃2⁃oxa⁃6⁃azaadamantane⁃4,8⁃diol dinitrate,was synthesized from 1,5⁃cyclooctadiene via oxidative cyclization,O⁃acylation,elimination,epoxidation,aminolysis and nitration with an overall yield of 20.7%.The single crystal structure of 6⁃nitro⁃2⁃oxa⁃6⁃azadamantane⁃4,8⁃diol dinitrate was obtained by X⁃ray single crys⁃tal diffraction.Its structure was characterized using NMR,IR,and elemental analysis.Thermogravimetric analysis(TG)and dif⁃ferential scanning calorimetry(DSC)were used to study the thermal stability of the target compound.Density functional theory method was used to study the detonation properties of the target compound.Result show that it has a density of 1.75 g·cm^(-3),a thermal decomposition temperature of 184℃,a detonation velocity of 7730 m·s^(-1),and a detonation pressure of 26.07 GPa.
