Densities and Speeds of Sound of Glycine, l-Alanine, and l-Valine in Aqueous 1-Ethyl-3-methylimidazolium Chloride Solutions at Different Temperatures

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 (ρ) 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.
