【摘要】 2,4-二硝基咪唑（2,4-DNI）是一种高能低感炸药,爆速8130 m·s^-1(p=1.77 g·cm^-3时),感度和TATB接近。其-NH上可以发生甲基化、胺化、偶氮化、离子化等多种反应,是构建新型含能化合物的重要结构单元。本文全面介绍了2,4-DNI的合成机理、方法及性能,概括了2,4-DNI典型的含能衍生物的合成方法。以2,4-DNI为基本结构单元,设计了7种含能化合物,并采用经验方法计算了设计化合物的爆轰特性参数,其中化合物V是一种高能量密度材料（HEDMs）。更多还原

【Abstract】 2,4-Dinitroimidazole（2,4-DNI） is an important explosive,its detonation velocity is 8130 m·s^-1(p = 1.77 g·cm^-3), and its sensitivity is close to TATB.At the same time,2,4-DNI has an active reaction position,-NH,which methylation,animation, zaoation,ionization and so form can take part in.It is a potential energetic moiety in the design and synthesis of high energy density materials.In this paper,the reaction mechanism,synthesis routes and properties of 2,4-DNI were reviewed comprehensively.Some representative derivatives Of 2,4-DNI were introduced.Seven novel compounds（a part of them were synthesized） were designed based on 2,4-DNI,and their detonation performance were calculated by empirical method.The results show that the designed compounds are of excellent performance,especially the calculated detonation velocities and density.更多还原
