ABSTRACT

The interactions of amino acids + water + 1-ethyl-3-methylimidazolium chloride [emim][Cl] solutions have been studied at different temperatures using volumetric and acoustic measurements. The density (?) and speed of sound (u) of glycine/l-alanine/l-valine + water + 1-ethyl-3-methylimidazolium chloride solutions have been measured at temperatures T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and experimental pressure of 0.1 MPa. The apparent molar properties, standard partial molar properties, and partial molar properties of transfer have been determined from experimentally measured densities and speeds of sound. The resulting values of V?0, ?V?0, K?,s0, and ?K?,s0 have been used to discuss the nature of interactions present in the mixtures. The apparent molar expansivity ?E0 and its temperature derivative (??E0/?T) have also been calculated.
