© 2018, Springer Science+Business Media, LLC, part of Springer Nature. New experimental vapor pressures and vaporization enthalpies of the ionic liquids [ C2mim][CF3CO2] and [ C4mim][CF3CO2] have been measured by the QCM method. The solution enthalpies of these ionic liquids were measured by using high-precision solution calorimetry and were used for calculation the aqueous enthalpy of formation ΔfHm∘(CF3CO2-,aq) of the anion for combination with quantum-chemical results. The solubility parameters of the ILs under study have been derived from experimental ΔlgHm∘(298.15 K) values and were used for estimation of miscibility of some common solutes with [ Cnmim][CF3CO2].
