采用离子交换法合成了4种六烷基胍3-硝基-1,2,4-三唑-5-酮(Cn-NTO,n=2,3,4,5)含能离子化合物,利用红外光谱(IR)和核磁共振(1HNMR)表征结构,对其溶解性、密度和热性能进行研究。结果表明,六烷基胍NTO离子盐在大多数有机溶剂中溶解性良好,最大分解温度在250℃左右,在DSC的二次升温过程中经历了玻璃态、过冷态、结晶固态和液态4种相态。
Four kinds of hexaalkylguanidine 3-nitro-1,2,4-triazol-5-ones (Cn-NTO, n = 2,3,4,5) were synthesized by ion exchange method. The structures were characterized by infrared spectroscopy (IR) and nuclear magnetic resonance (1HNMR), and their solubility, density and thermal properties were studied. The results show that hexaalkylguanidinium NTO ion salt has good solubility in most organic solvents, the maximum decomposition temperature is about 250 ℃, and it undergoes glassy, supercooled, crystalline solid and liquid 4 Kind of phase.
