This work investigates a simple synthetic method for producing fused dinitromethyl energetic compounds. Fused compound has a high detonation velocity (9358 m s) close to that of the well-known high-energy-density explosive CL-20 (9455 m s), an extremely high density (1.97 cm), and acceptable sensitivity (IS = 8 J). The good thermal stability of ( = 181 °C) is rarely reported in the field of dinitromethyl-based high explosives. The results show that compound is a promising candidate for high explosives and provide new insight into the synthesis of dinitromethyl compounds.
本工作研究了一种制备稠合二硝基甲基含能化合物的简单合成方法。稠合化合物具有接近著名的高能量密度炸药CL-20（9455米/秒）的高爆速（9358米/秒）、极高的密度（1.97克/立方厘米）和可接受的感度（撞击感度=8焦耳）。该化合物良好的热稳定性（热分解温度=181℃）在二硝基甲基类高能炸药领域鲜有报道。结果表明，该化合物是一种很有前景的高能炸药候选物，并为二硝基甲基化合物的合成提供了新的见解。
