Osmotic and activity coefficients in the binary solutions of 1-butyl-3-methylimidazolium chloride and bromide in methanol or ethanol at T=298.15K from isopiestic measurements

Activity Coefficients of [Cnmim]Br (n = 3 to 8) Ionic Liquids in Aqueous Fructose Solution at T = 298.15 K

“…Several authors have reported activity coefficients of some organic solutes (pure substance as the standard state) in ILs by gas–liquid chromatography. − Sardroodi et al and Zafarani-Moattar and Sarmad determined activity coefficients of ILs in alcohols and aqueous solutions of potassium salts by isopiestic measurements, respectively. However, to the best of our knowledge, the activity coefficients of ILs in aqueous saccharide solutions have been rarely reported in the literature.…”

Isothermal Vapor + Liquid Equilibrium and Thermophysical Properties for 1-Butyl-3-methylimidazolium Bromide + 1-Butanol Binary System

“…ILs have been used, for example, as green entrainers with a salting-out effect in extractive distillation, as highly efficient solvents in organic synthesis, and as catalysts for phase transfer. In recent years, many authors have presented various aspects of these materials. − A literature survey shows an increased trend in studies on the pure ILs and their mixtures (ion mobilities, glass temperatures and fragilities, different thermodynamic properties, osmotic coefficients, − and phase equilibria ,, ). These studies help engineers to design, understand, and control the industrial processes including ionic liquids, and researchers to tailor their chemical structure so that to better match a given target .…”
