behavior of the alkali salts of these amides is studied by thermoanalytical experiments. Moreover, several novel ionic liquids based on resonance stabilized amides have been prepared and were fully characterized, namely the dfa, fca, and nca salts of EMIM (1‐ethyl‐3‐methyl‐imidazolium), BMIM (1‐butyl‐3‐methyl‐imidazolium), and HMIM (1‐hexyl‐3‐methyl‐imidazolium). Most of them are liquid at room temperature
在此基础上,讨论了共振稳定酰胺(例如二甲酰胺(dfa),甲酰基氰酰胺(fca),硝基氰酰胺(nca))的碱金属盐的合成,结构和键合。实验和理论数据。K(18-冠-6)的第一结构报告+ DFA -,K(18-冠-6)+ FCA - ,钠+ NCA -和Li(TMEDA)+ DCA -被提出。通过X射线数据检查,可以发现几乎平面的阴离子具有强的阳离子-阴离子相互作用,从而形成固态的网络状结构。为了进行比较,还讨论了共价键合的苯基二氰胺和二甲酰胺的X射线结构。通过热分析实验研究了这些酰胺的碱金属盐的热行为。此外,已经制备了几种基于共振稳定酰胺的新型离子液体并进行了充分表征,分别是EMIM(1-乙基-3-甲基咪唑鎓),BMIM(1-3丁基-3-甲基咪唑)的dfa,fca和nca盐。甲基咪唑鎓)和HMIM(1-己基-3-甲基咪唑鎓)。他们大多是在室温下是液体,除了BMIM + FCA -在32°C熔
