ABSTRACT

Refractive indices for six binary systems formed by three pyridinium-based ionic liquids:1-butylpyridinium tetrafluoroborate, 1-butyl-3-methylpyridinium tetrafluoroborate or 1-butyl-4-methylpyridinium tetrafluoroborate and two alkanols: methanol or ethanol were measured at fourtemperatures, T = 293.15, 303.15, 313.15 and 323.15 K. From these data excess refractive indices werecalculated and fitted. The excess refractive indices of the mixtures, which were found positive, wererelated to their corresponding excess volumes. Furthermore, several mixing rules were used to predictboth refractive indices and densities of the binary mixtures.
