Thermophysical Properties of 1-Propyronitrile-3-alkylimidazolium Bromide Ionic Liquids at Temperatures from (293.15 to 353.15) K
In the present work, a series of 1-propyronitrile-3-alkylimidazolium bromide ionic liquids ([C2CN Cnim]Br, where n ) 4, 6, 8, and 10) were synthesized and characterized using Fourier transform infrared spectroscopy (FTIR), NMR, and elemental analysis. Physical properties such as density, viscosity...

| 總結: | In the present work, a series of 1-propyronitrile-3-alkylimidazolium bromide ionic liquids ([C2CN Cnim]Br,
where n ) 4, 6, 8, and 10) were synthesized and characterized using Fourier transform infrared spectroscopy
(FTIR), NMR, and elemental analysis. Physical properties such as density, viscosity, and refractive index
are measured and reported for a temperature range of (293.15 to 353.15) K and at atmospheric pressure.
The influence of the alkyl chain on these properties is discussed. The present synthesized ionic liquids show
a weak temperature dependency on the thermal expansion coefficient. |
