calculation of the theory of thermodynamic properties of ionic liquids in pure and mixed state

Ionic liquids are defined as moltensalts consisting of cations and anions.the structures and properties of ionicliquids are controlled by the interactionsbetween the ions, so understanding therelationship between these interactions andthe properties is essential to the design(group contribution method) of ionicliquids. in this article at first, 10 ionicliquids containing metal have beenselected. in the second stage, the criticalparameters have been calculated by thegroup contribution method. equations forcalculating the viscosity of ionic liquidscontaining different anions at differenttemperatures and molar fractions havebeen used.
