Volumetric properties of ionic liquids, 1-Ethyl-3-ethylimidazolium chloride [Emim][Cl] and 1-ethyl-3-methylimidazolium hydrogen sulfate [Emim][HSO4] in sucrose aqueous solutions at T = (293.15 to 313.15) K and ambient pressure
The solute e solvent interactions considered in ternary systems ([Emim][Cl] + sucrose + H2O), ([Emim] [HSO4] + sucrose + H2O) and binary systems ([Emim][Cl] + H2O), ([Emim][HSO4] + H2O). For this purpose, the apparent molar volumes, Vf calculated from experimental density data. To obtain limiting apparent molar volumes Vf0 , the Redlich-Meyer type of equation fitted to apparent molar volume values. Then the limiting apparent molar volumes of transfer, DtVf 0 , for studied ionic liquids (ILs) from water to aqueous solutions of sucrose calculated and their values were negative for all systems. The values of limiting apparent molar expansibility, Ef0 , obtained from first derivative of limiting apparent molar volumes with respect to temperature. The values of second derivative of limiting apparent molar volumes with respect to temperature indicated that both ionic liquids act as structure maker in studied solutions. Also results confirm that ion-ion interactions are stronger than ion-solvent interactions in these solutions.
