目前,有毒和挥发性肼衍生物仍是液体双推进剂的主要燃料选择,尤其是在某些传统的火箭推进系统中。因此,寻找更安全的高取代氢燃料替代肼衍生物一直是最具挑战性的任务之一。在这项研究中,已合成并表征了六种具有两性离子结构的咪唑基亚烷基-硼烷化合物,并对其超高活性进行了研究。如所期望的,这些化合物在与白色发烟硝酸(WFNA)接触时表现出快速的自燃。其中,化合物5具有出色的综合性能,包括宽的液体工作范围(-70–160°C),优异的装载密度(0.99 g cm -3),使用WFNA的超快点火延迟时间(15毫秒)和高比冲(303.5 s),这表明在液体双推进剂配方中作为更安全的高离岸燃料,有广阔的应用前景。

The supramolecular polymeric aggregation behaviour of these ILs has been studied through high-resolution electron spray ionization mass spectrometry (HR-ESI-MS). Furthermore, these ILs were applied as catalyst/phase transfer catalyst in the synthesis of tetrahydrobenzo[b]pyran and its derivatives. These reactions were conducted in aqueous medium under ultrasound assistance. The results suggested that
天然存在的苯甲酸 (BA) 衍生阴离子已被用于制备无卤素亲水性离子液体 (ILs 1-4)。这些 IL 的超分子聚合物聚集行为已通过高分辨率电子喷雾电离质谱 (HR-ESI-MS) 进行了研究。此外,这些 ILs 被用作催化剂/相转移催化剂合成四氢苯并[b]吡喃及其衍生物。这些反应在超声辅助下在水性介质中进行。结果表明,1-乙基-3-甲基咪唑鎓 2-羟基苯甲酸酯 (IL-1) 是一种高效的催化剂,在 30 分钟内产生 86.9% 的产物。此外,还研究了 ILs 的聚集行为对其催化活性的影响。

We report the synthesis and characterization of a series of imidazolium iodide ionic liquids (ILs) containing monomethoxy-terminated poly(ethylene glycol) (mPEG), and n-alkyl groups. These PEGylated ILs contain 7, 12, or 16 ethylene glycol units in the sidechains, and are designed as potential electrolytes for energy conversion and storage devices such as dye-sensitized solar cells, supercapacitors
