Surface Tension Prediction of Ionic Liquid Binary Solutions

01-12-2014 | Ensieh Ghasemian Lemraski; Zohre Pouyanfar, Journal of Chemical & Engineering Data, 2014

An ionic liquid is a salt in which the ions are poorly coordinated, which results in these solvents being liquid below 100 °C, or even at room temperature. At least one ion has a delocalized charge, and one component is organic, which prevents the formation of a stable crystal lattice. In the ...


Stable Phase Equilibrium of Aqueous Quaternary System Li+, K+, Mg2+//Borate–H2O at 348 K
