摘要
含能材料是指在一定外界条件刺激下,能发生激烈氧化还原反应并释放大量能量的物质。按其用途可分为炸药、推进剂、燃料和烟火剂等,它们在国防工业和国民经济领域有着重要作用~([1])。近年来,含能离子盐因为具有较低的蒸汽压、热稳定性好等优点而备受关注~([2])。然而,含能离子盐的前体来自于人工合成的唑类等有机小分子,存在着原料来源有限、制备复杂等缺点,特别是其合成过程中仍会产生一定的环境污染问题~[3]。使用生物可再生原料是实现环境保护的一种有效方法。我们以自然界广泛存在的氨基酸为原料,通过温和的反应制备了具有含能性质的氨基酸离子液体。通过不同组分结构的筛选,氨基酸离子液体的性质可以被有效调控,能由完全不能燃烧转变为具有良好的燃烧性能,其能量性质如密度、热分解温度、燃烧焓和爆压、爆速等都可以被进一步优化。经过结构优化,我们获得的钝感的氨基酸离子液体在相同测试条件下展现出优于常见的TNT、RDX、HMX等重要含能化合物的能量性能。
Energetic materials with large amounts of stored energy that can be released under specific conditions are of crucial importance to human life. They have been used in explosives, propellants, fuels and pyrotechnics. Recently, ionic energetic materials have attracted considerable attentions because of their little vapor toxicity compared with the traditional energetic compounds. However, recent studies have shown that some energetic salts are harmful to environment due to the high energy consumption of manufacture of their precursors. Alternatively, biomolecules can be used as raw materials to mitigate the effect on the environment. Herein, a series of amino acid ionic liquids were synthesized by one step without any by-product. The infrequent energetic properties of amino acid ionic liquids can be obtained by regulation of the cation's and anion's structure formation. The energetic properties of these insensitive amino acid ionic liquids are better than conventional TNT, RDX, HMX at the same test conditions.
