六烷基胍NTO含能盐的合成与表征

摘要

Four kinds of hexaalkylguanidinium 3-Nitro-l ,2,4-triazole5-one(Cn-NTO,N =2,3,4,5) energetic ionic compounds were synthesized. Their structures were identified by IR,'HNMR,and their density,solubility, thermal properties were studied. The results show that NTO hexaalkylguanidinium ionic salts could dissolve in most of organic solvents. The maximum decomposition temperature is about 250 ℃. In the second heating process of DSC,the NTO ionic salts experienced four kinds of phases,I. e. glassy, supercooled state, crystalline solid and liquid.%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(1 HNMR)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.
