摘要

这项工作研究了一种生产熔融二硝基高能化合物的简单合成方法。熔融化合物 2 的起爆速度（9358 m s-1）接近著名的高能量密度炸药 CL-20（9455 m s-1），密度极高（1.97 cm-1），灵敏度可接受（IS = 8 J）。2 具有良好的热稳定性（Td = 181 °C），这在以二硝基甲基为基础的高能炸药领域很少见报道。研究结果表明，化合物 2 是一种很有前途的候选高爆炸药，并为二硝基甲基化合物的合成提供了新的见解。

A Method for the Preparation of Fused Dinitromethyl High-Energy-Density Materials

This work investigates a simple synthetic method for producing fused dinitromethyl energetic compounds. Fused compound 2 has a high detonation velocity (9358 m s^–1) close to that of the well-known high-energy-density explosive CL-20 (9455 m s^–1), an extremely high density (1.97 cm^–1), and acceptable sensitivity (IS = 8 J). The good thermal stability of 2 (T_d = 181 °C) is rarely reported in the field of dinitromethyl-based high explosives. The results show that compound 2 is a promising candidate for high explosives and provide new insight into the synthesis of dinitromethyl compounds.
