1,1–二氨基–2,2–二硝基乙烯的研究现状

Research Status of 1,1-Diamino-2,2-Dinitroethylene

介绍了近年来1,1–二氨基–2,2–二硝基乙烯(FOX–7)的合成与应用、相转变、热性能、衍生物及相关理论研究等方面的研究成果。FOX–7具有优良的综合性能,与火药和炸药主要组分相容性良好,可应用于低敏感火药和炸药的研制;其分子中的硝基和氨基赋予了它良好的反应性,为新型含能材料的开发开辟了新途径;在不同的实验条件下,FOX–7表现出不同的热响应,在受限于纳米晶体多孔材料的条件下,其热稳定性较高。

The recent research results on the synthesis, application, phase transition, thermal performance, derivatives and relative theory, etc. of 1,1-diamino-2,2- dinitroethylene （FOX-7） are introduced. FOX-7 can be used to manufacture low sensitive gunpowder and explosive because it has excellent general performance and good compatibility with main com- ponents of gunpowder and explosive. The nitro and amino groups in FOX-7 molecule give it good reactive characteristics and provide a new path for developing novel energetic materials. Under different experimental conditions, FOX-7 exhibits different thermal responses. The thermal stability of FOX-7 is higher when it is limited to condition of nano crystal porous materials.
