Industrially, molybdenum (Mo) is very useful metal. molybdenum extraction process used selective solvent as amine or ketone type solvents. The thermodynamics properties data for ketone type solvent and phosphonium based ionic liquids are required to develop molybdenum extraction process. The study of thermodynamic properties of the liquid mixture and pure components is very essential in the design of various physical and chemical processes, especially for a new class of substance such as ionic liquid. In this work, the excess and deviation properties, such as the excess molar volumes (VE) and deviation of refractive indices (∆R) for the binary mixtures, {MEK + Phosphonium based Ionic liquids}, {MIPK + Phosphonium based Ionic liquids} were determined at 298.15 K over the entire composition range. The experimental data were satisfactorily fitted with the Redlich-Kister polynomial. |
