ABSTRACT
The liquid liquid equilibria of two binary systems containing 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide with butan-1-ol or hexan-1-ol at atmospheric pressure have been investigated. The two-phase line was observed as function of temperature using light scattering or visual detection. In addition, other physical properties such as the densities of phases in equilibrium and the interfacial tension were determined. The results obtained were compared with the literature and briefly discussed in terms of possible interactions that may occur in ionic liquid + alkan-1-ol solutions.
