Abstract

Density, speed of sound, refractive index, and dynamic viscosity of the ionic liquids (ILs) 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, BMpyr NTf2, and trihexyl(tetradecyl) phosphonium dicyanamide, P-66614 dca, were studied as a function of temperature at atmospheric pressure. Thermal expansion coefficient, alpha(p), molecular volumes, and standard entropies of these ILs were calculated from the experimental density values. The solubility of three aromatic components (benzene, toluene, and ethylbenzene) in the selected ILs was carried out at T = 298.15 K and atmospheric pressure and compared with literature values for sulfolane.
