Abstract

Single-compound heat-resistant explosives are an important class of high-energy compounds with excellent thermal stability. In this paper, a novel thermally stable explosive 3,5-dinitro-N²,N⁶-bis(2,4,6-trinitrophenyl)pyrazine-2,6-diamine (ZXC-71) is reported. The commercially available 2,6-dichloropyrazine was used as raw materials to prepare this compound with a straightforward method. The crystalline structure of ZXC-71 was determined by single-crystal X-ray diffraction. From the calculated standard molar enthalpy of formation and the measured density, the Chapman–Jouguet detonation properties were predicted. The detonation velocity (D), detonation pressure (P), and density (ρ) of ZXC-71 are 8608 m s⁻¹, 29.8 GPa, and 1.86 g cm⁻³, respectively. ZXC-71 also exhibits remarkable impact sensitivity (FS=22 J).

3,5-二硝基-N2,N6-双(2,4,6-三硝基苯基)吡嗪-2,6-二胺（ZXC-71）：性能卓越的热稳定炸药

单化合物耐热炸药是一类重要的高能化合物，具有优异的热稳定性。本文报道了一种新型热稳定性炸药 3,5-二硝基-N2,N6-双（2,4,6-三硝基苯基）吡嗪-2,6-二胺（ZXC-71）。该化合物以市售的 2,6-二氯吡嗪为原料，采用简单的方法制备而成。通过单晶 X 射线衍射测定了 ZXC-71 的晶体结构。根据计算的标准摩尔形成焓和测量的密度，预测了 Chapman-Jouguet 起爆特性。ZXC-71 的起爆速度（D）、起爆压力（P）和密度（ρ）分别为 8608 m s-1、29.8 GPa 和 1.86 g cm-3。ZXC-71 还具有显著的冲击灵敏度（FS=22 J）。

期刊介绍： Propellants, Explosives, Pyrotechnics (PEP) is an international, peer-reviewed journal containing Full Papers, Short Communications, critical Reviews, as well as details of forthcoming meetings and book reviews concerned with the research, development and production in relation to propellants, explosives, and pyrotechnics for all applications. Being the official journal of the International Pyrotechnics Society, PEP is a vital medium and the state-of-the-art forum for the exchange of science and technology in energetic materials. PEP is published 12 times a year. PEP is devoted to advancing the science, technology and engineering elements in the storage and manipulation of chemical energy, specifically in propellants, explosives and pyrotechnics. Articles should provide scientific context, articulate impact, and be generally applicable to the energetic materials and wider scientific community. PEP is not a defense journal and does not feature the weaponization of materials and related systems or include information that would aid in the development or utilization of improvised explosive systems, e.g., synthesis routes to terrorist explosives.
