Investigations of (solute-solute) and (solute-solvent) interactions in ternary {amino acids + 1-dodecyl-3-methylimidazolium bromide [C12mim] [br] + water} mixtures at different temperatures

Density and speed of sound of an aqueous solution of glycine and L-valine containing 1-dodecyl-3-methylimidazolium bromide, [C12mim] [Br], have been determined at T= (288.15 K to 308.15 K). From experimental density, the apparent molar volumes (Vϕ), the apparent molar volumes at infinite dilution (Vϕ0) and partial molar volume of transfer ΔVϕ0have been calculated. The values of apparent molar volumes (Vϕ) are positive for both glycine and...
