Thermodynamics of dilute aqueous solutions of imidazolium based ionic liquids

Volumetric studies to examine the interactions of imidazolium based ionic liquids with water by means of density and speed of sound measurements

“…So, the apparent molar isentropic compressions were calculated from the measured densities and speeds of sound using equations (9), (10), (1) and then (8) successively.…”

“…Although a fair amount of data on the thermophysical properties of ionic liquids in pure form has been published [5][6][7], systematic studies for properties of their aqueous solution as functions of temperature and concentration are very scarce and limited to some imidazolium based ionic liquids [8][9][10].…”

Physicochemical properties of an anticonvulsant drug sodium valproate in aqueous and in mixed aqueous solutions at different temperatures

“…The confirmation of the same is evidenced from the rupture of water-water bond after decrease in hydration number. On increasing the temperature, the water-water bonds are broken resulting in decrease in hydration number [62]. …”

Influence of water concentration in the viscosities and densities of cellulose dissolving ionic liquids. Correlation of viscosity data

“…Rebelo and co-workers [7] measured the densities and speed of sound of C 8 , C 10 and C 12 -mimCl ILs in diluted aqueous solutions at temperature range from (283.15 to 313.15) K to prove the self aggregation phenomena of long chained alkylimidazolium chloride ILs. Gómez et al [8] determined densities and viscosities of mixtures (water + C 4 , C 6 and C 8 -mimCl ILs) at temperatures from (298.15 to 343.15) K. Liu et al [9] studied densities and viscosities of binary mixtures (water + 1-butyl-3-methylimidazolium chloride (C 4 mimCl) + water) at T = 298 K. Sing and Kumar [10] determined densities and viscosities of diluted aqueous solutions C 4 mimCl and C 8 mimCl in water. Calvar et al [11] studied the physical properties of the ternary mixture (ethanol + water + C 4 mimCl).…”
