摘要

为了克服3-硝基-1,2,4-三唑-5-酮（NTO）的酸性,设计了新的含能离子化合物3-硝基-1,2,4-三唑-5-酮脒基脲盐（GUNTO）,以NTO和脒基脲盐酸盐为原料,采用一锅法和分步法两种方法合成了GUNTO,收率均高于85%。用红外光谱、核磁共振、质谱、元素分析和X-射线单晶衍射表征了它的结构。研究了GUNTO的物化性质与爆轰性能。借助晶体密度1.72 g·cm^-3和理论计算的生成焓-347.35 kJ·mol^-1,运用Kamlet公式预估爆速为6683.49 m·s^-1、爆压为19.27 GPa。实测撞击感度、摩擦感度均为0%,特性落高H50大于125.8 cm,10℃·min^-1时DSC曲线的峰温为236.8℃。与其他NTO胺盐相比,GUNTO氮含量较高、热稳定性好、感度低。
