AB In this study, a physical characterization (density (q), refractive index (nD), speed of sound (u) anddynamic viscosity (g)) as a function of temperature (298.15–343.15 K) of choline glycinate (ChGly) andits binary mixtures with water or/and methanol over the entire composition range was performed from298.15 K to 323.15 K. Several derived properties of the pure ionic liquid and excess molar volume (VEm) changes of refractive index on mixing (DnD), deviations in isentropic compressibility (DjS) and viscositydeviations (Dg) have been calculated using the experimental data in the selected temperature range.These experimental data of ChGly have been positively correlated using polynomial equations and thederived magnitudes were successfully fitted to Redlich-Kister equation. Finally, different models havebeen implemented for the first time to predict the density of the selected binary mixtures as a functionof the temperature.
