Thermodynamic Properties of Mixtures Containing Ionic Liquids. 3. Liquid-Liquid Equilibria of Binary Mixtures of 1-Ethyl-3-methylimidazolium Bis(trifluoromethylsulfonyl)imide with Propan-1-ol, Butan-1-ol, and Pentan-1-ol

ABSTRACT
An apparatus for measuring liquid-liquid equilibria of small samples of liquid mixtures with relatively high differences in density and viscosity was applied for studying mixtures of the ionic liquid 1-ethyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide and the three alcohols propan-1-ol, butan-1-ol, and pentan-1-ol. The synthetic method has been applied where cloud points at a given composition were determined by varying the temperature. The point of phase splitting was detected by light scattering. Data in the temperature range 281 K to 340 K have been obtained for the three systems.
