"Mutual solubilities of pyridinium-based tetrafluoroborates (namely: 1-butylpyridinium tetrafluoroborate, 1-butyl-2-methylpyridinium tetrafluoroborate, 1-butyl-4-methylpyridinium tetrafluoroborate and 1-hexylpyridinium tetrafluoroborate) and toluene were obtained at (298.15, 318.15 and 338.15) K. The data were acquired by means of an experimental procedure utilizing gas chromatography and a gravimetric method. The results show that the liquid?liquid equilibrium in the studied systems is strongly asymmetrical. While mole fraction solubility of the pyridinium-based ionic liquids in toluene ranges from 1.0 x 10?5 to 5.2 x 10?5, the solubility of toluene in these ionic liquids varies from 0.318 to 0.579 in mole fraction. The experimental data were correlated with a semiempirical equation. Parameters of the NRTL equation were evaluated as well." . "3"^^ . "US - Spojen\u00E9 st\u00E1ty americk\u00E9" . . .
