Influence of water and ethanol in the physical properties of choline glycinate at several temperatures

In this study, a physical characterization (density ( ρ ), refractive index n D speed of sound u ) and dynamic viscosity η )) as function temperature (298.15–343.15 K) choline glycinate (ChGly) its binary mixtures with water or/and methanol over the entire composition range was performed from 298.15 K to 323.15 K. Several derived properties pure ionic liquid excess molar volume V m E changes on mixing (Δ deviations in isentropic compressibility κ S have been calculated using experimental data selected range. These ChGly positively correlated polynomial equations magnitudes were successfully fitted Redlich-Kister equation. Finally, different models implemented for first time predict density temperature.
