ABSTRACT
The density and surface tension for the binary mixtures of ionic liquid (ILs) [C22O1IM][TfO] with ethanol, 1-propanol and 2-propanol are measured across the entire range of mole fraction at T = (288.15-318.15) K. The excess molar volumes of the binary mixtures are calculated, the relationship between VE and the mole fraction and temperature are explored. Especially, the term, DeltaVE/DeltaT is proposed to describe the interaction between the solvent and solute quantificationally. The molar surface Gibbs energy of the binary mixtures are obtained based on the density and surface tension, and the interaction between the components in both liquid and surface phase of the binary mixture is discussed. And its applications are also explored, including the estimation of surface tension for the binary mixtures and the improvement of the traditional Eoetvoes equation. At the same time, the polarity of the binary mixtures of [C22O1IM][TfO] with alcohols is obtained.
