An Improved ISM Equation of State for Polar Fluids
We developed an equation of state (EOS) by Ihm, Song, and Mason (ISM) for polar fluids. The model consists of four parameters, namely, the second virial coefficient, an effective van der Waals co-volume, a scaling factor, and the reduced dipole moment. The second virial coefficient is calculated from a correlation that uses the heat of vaporization, and the liquid density at the normal boiling ...
متن کاملDERIVING THE EQUATION OF STATE FOR LIQUIDS AND EXTENSION OF THE PRINCIPLE OF CORRESPONDING STATES
A new simple model is introduced for a liquid and an equation of state is derived based on this model and the statistical mechanical calculations. This equation of state works well for the non-polar and slightly polar liquids. The important conclusion that may be deduced from this equation of state is that if the reduced variables of state are chosen and defined appropriately, then, the pri...

متن کاملA high temperature equation of state for the H2O-CaCl2 and H2O-MgCl2 systems
An equation of state (EOS) is developed for salt-water systems in the high temperature range. As an example of the applications, this EOS is parameterized for the calculation of density, immiscibility, and the compositions of coexisting phases in the CaCl2-H2O and MgCl2-H2O systems from 523 to 973 K and from saturation pressure to 1500 bar. All available volumetric and phase equilibrium measure...
متن کاملIonic liquids as solvents of polar and non-polar solutes: affinity and coordination.
The use of ionic liquids (ILs) as highly tuneable solvents requires a deep understanding of the intermolecular interactions they can establish with the solutes. In the present work, we study the solvation patterns of two small but highly important molecules in the framework of IL properties and applications, namely H2O and CO2. Density functional theory (DFT) and ab initio molecular dynamics (A...
