Thermophysical Properties of Ionic Liquid with Thiocyanate Anion: Effect of Cations

Abstract:

Article Preview

In the present work, four ionic liquids containing thiocyanate anions with different cations were synthesized, and some of their thermophysical properties were measured. The density of the ionic liquids were measured in the temperature range of T = (293.15 to 353.15) K. The thermal expansion coefficient values were obtained from the experimental density values. The molar volume, lattice energy, and standard entropy of the ionic liquids were calculated from the experimental results. A thermogravimetric analyzer (TGA) was used to investigate the thermal degradation behavior of synthesized ionic liquids. The effects of temperature and nature of cations on the thermophysical properties were presented.
