Abstract

Hydrazine and its derivatives have served as a conventional bipropellant fuel for several decades. However, their extremely acute toxicity and carcinogenicity, high volatility, and environmental impact have attracted significant attention. In order to synthesize green bipropellant fuels with high density, high specific impulse, and good thermal stability, three novel N-alkyl-1,2,4-triazole–borane complexes were successfully synthesized by reacting alkylated 1,2,4-triazole coordinated with sodium borohydride in the presence of ammonium sulfate. During the droplet test with white fuming nitric acid, there was a relatively short ignition delay time of 98 ms. Additionally, these hypergolic fuels possessed a high density exceeding 1.10 g cm–3, and the specific impulse is ranging from 187 to 199 s, and the highest decomposition temperature reaches 153.4 °C. These results demonstrate their great potential as hypergolic fuels or hypergolic ionic liquid additives in the field of hypergolic materials.

作为高密度超醇材料的 N-烷基-1,2,4-三唑-硼烷络合物
几十年来,肼及其衍生物一直是传统的双推进剂燃料。然而,它们的剧毒性和致癌性、高挥发性以及对环境的影响引起了人们的极大关注。为了合成具有高密度、高比冲和良好热稳定性的绿色双推进剂燃料,研究人员通过在硫酸铵存在下使烷基化的 1,2,4 三唑与硼氢化钠反应,成功合成了三种新型 N-烷基-1,2,4-三唑-硼烷复合物。在用白色发烟硝酸进行液滴测试时,点火延迟时间相对较短,仅为 98 毫秒。此外,这些双酚燃料的密度超过 1.10 g cm-3,比冲为 187 至 199 s,最高分解温度达到 153.4 ℃。这些结果证明了它们作为超醇燃料或超醇离子液体添加剂在超醇材料领域的巨大潜力。
