| 摘 要： | 以N,N-二烷基咪唑(Cx-imi,x=3,4,5,6)为阳离子,3-硝基-1,2,4-三唑-5-酮(NTO)为阴离子合成了4种离子液体,利用元素分析、红外光谱和核磁共振表征其结构,并测定了其溶解性、密度、热性能和黏度。结果表明,NTO烷基咪唑离子液体在乙腈、N,N-二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)等介电常数较大的有机溶剂中溶解性较好,密度在1.897g/cm3以上,固相到液相的热转变温度在-34.4℃以下,5%的热失重在220℃左右,热稳定性较好。

| Abstract: | Ionic liquids were synthesized by N,N-dialkyl imidazole(Cx-imi,x=3,4,5,6) for the cation,and 3-nitro-1,2,4-triazole-5-one(NTO) for the anionic.Their structures were identified by IR,1 H NMR,elemental analysis,and their density,solubility,viscosity,thermal properties were studied.The results showed that NTO-alkyl imidazolium ionic liquids dissolve in acetonitrile,DMF,DMSO and other organic solvents with larger dielectric constant.Their density were greater than 1.897 g/cm3,thermal transition temperatures of ... |
