Over the past few decades, toxic and highly volatile hydrazine derivatives have been the main fuel choices for liquid bipropellants, especially in traditional hypergolic rocket engines. The search for new hypergolic fuels as replacements for hydrazine derivatives is of great interest to researchers. In this study, a series of N-alkylimidazole borane compounds has been synthesized and characterized. Interestingly, these compounds display promising applications as potential hypergolic fuels owing to their excellent physiochemical properties including low melting points, high thermal stability, low viscosities, and unique hypergolic reactivity. Compared with popular hypergolic ionic liquids, the cost-effective and scaling-up advantages of these materials highlight their promising potential as high-performance fuels in liquid bipropellant formulations.
在过去几十年里，有毒且高挥发性的肼衍生物一直是液体双组元推进剂的主要燃料选择，尤其是在传统自燃火箭发动机中。寻找新型自燃燃料来替代肼衍生物是研究人员非常感兴趣的课题。在本研究中，一系列N - 烷基咪唑硼烷化合物已被合成并表征。有趣的是，这些化合物由于其优异的物理化学性质，包括低熔点、高热稳定性、低粘度和独特的自燃反应活性，显示出作为潜在自燃燃料的应用前景。与常见的自燃离子液体相比，这些材料具有成本效益高和可放大生产的优势，突出了它们在液体双组元推进剂配方中作为高性能燃料的潜在前景。
