| Summary: | In this work, some new dual functionalized imidazolium based ionic
liquids 3 (3 butyl 1H imidazol 3 ium 1 yl)propanenitrile chloride [C2CNBim]Cl, 3 (3
allyl 1H imidazol 3 ium 1 yl)propanenitrile chloride [C2CNAim]Cl, 3 [3 (2 hydrox
yethyl) 1H imidazol 3 ium 1 yl]propanenitrile chloride [C2CNHEim]Cl, and 3 (3
benzyl 1H imidazol 3 ium 1 yl)propanenitrile chloride [C2CNBzim]Cl have been
synthesized and characterized by 1H NMR, FTIR, and elemental analysis. Their
thermophysical properties such as viscosity and density were measured for a
temperature range of (293.15 to 353.15) K at atmospheric pressure, and their
refractive indices were measured in the range of (293.15 to 333.15) K. The effect of
functionalized side chains on their thermophysical properties was studied. The thermal
expansion coefficient values were calculated using experimental density values. Thermal
behavior of these ionic liquids was investigated using a thermogravimetric analyzer
(TGA) and differential scanning calorimetry (DSC).
