摘要: Abstract Several new monocationic and unsymmetrical dicationic azide functionalized ionic liquids (ILs) were synthesized. FT-IR, 1H NMR, 13C NMR elemental analyses applied to identify the molecular structure of these compounds. The density was measured too. Unsymmetrical had higher than analogues. shear viscosity a liquid ((1-(2-azido-3-methyl-3H-imidazole-1-ium) propyl)-3-vinyl-3H-imidazole-1-ium di-dicyanamide) its corresponding analogue also measured. Further thermal behaviour heat capacity this investigated by TGA DSC techniques. analysis suggested that decomposition temperature increases with increasing heating rate has good stability (up 502.4–533.6 K) (298–343 K).
