A Fluctuation Equation of State for Prediction of High-Pressure Densities of Ionic Liquids

Abstract During this work, we demonstrate, for the first time, that the volumetric properties of pure ionic liquids could be truly predicted as a function of temperature from 219 K to 473 K and pressure up to 300 MPa. This has been achieved by using only density and isothermal compressibility data a...
