چکیده انگلیسی
Deep eutectic solvents (DESs) are emerging as innovative materials and regarded as cost effective IL replacements. Mixing of DESs with other solvents modifies their properties for specific applications. One of the popular DESs is made of choline chloride and glycerol named as glyceline. Densities of glyceline mixed with water, methanol, ethanol, or iso-propanol were measured in the temperature range of 283.15 to 343.15 or 323.15â¯K over the entire range of composition at ambient pressure. The temperature dependency was correlated by a quadratic equation for the respective systems. The excess molar volumes were evaluated and correlated by a Redlich-Kister type equation with temperature-dependent parameters. Furthermore, other derived volumetric properties such as the volume expansivity and the apparent molar volume were calculated using the measured data. The H-bond formation is more likely to occur in alcohol solutions than in aqueous solution as inferred by the comparison of the maximum deviations from ideal mixing and the limiting apparent molar volume of glyeline in the solutions.
