摘要: Abstract Novel dual dicyanamide-based ionic liquids consisting of coupled ammonium–imidazolium cationic structures were synthesized and their thermal properties studied. The molecular these compounds identified by NMR, FT-IR CHN analysis. Viscosity measurements showed that the new liquid with vinylimidazolium group has lower viscosity than methylimidazolium group. However, densities are almost same. Thermal behaviors heat capacities also investigated thermogravimetry (TGA) differential scanning calorimetry (DSC). results suggest have stabilities up to 200 °C, as well reasonable in range 25 100 °C.
