Ionic liquids (ILs) or melting organic salts belong to the special type of fluid thermodynamic systems in which the orthobaric (saturated) vapor phase is practically absent at low (working) temperatures located below the thermal decomposition point. The methodology of FT-(fluctuational thermodynamics) model developed by author and applied to this complicated object (considering by many theoreticians and simulators as an example of ionic fluid behavior) reveals about all typical features of usual neutral systems. In particular, such important for the construction of IL-EOS (equation of state) parameters as the location of virtual critical point, the shape of hypothetical phase diagram and the normal boiling point can be predicted, at least, in the thermodynamically-consistent manner by the proposed FT-approach. The book is recommended for the wide circle of chemists and physicists exploited in their work the remarkable quite useful and often unusual properties of ILs.
