Physical properties of the ternary mixture ethanol plus water plus 1-hexyl-3-methylimidazolium chloride at 298.15 K

In this work, densities and refractive indices of the ternary mixture ethanol + water + 1-hexyl-3-methylimidazolium chloride ([C(6)mim][Cl]) and of the binary systems containing the ionic liquids (ILs) have been measured at 298.15 K and atmospheric pressure. Excess molar volumes and changes of refractive indices on mixing were determined from experimental data. The binary data were correlated with the Redlich-Kister equation, while the Cibulka equation was applied for the ternary system.
