Compared with the conventional Ionic Liquids, Deep Eutectic Solvents (DES) are more biodegradable and biocompatible. Moreover, they are easily prepared with high purity at low cost. Because of this, an extensive study of both properties of pure DES and of their binary mixtures with alcohols, in function of temperature is very necessary and of considerable importance for the development and design of new processes using these solvents. Density, speed of sound, refractive index and viscosity of choline chloride and levulinic acid DES pure and their mixtures with alcohols have been studied at several temperatures and atmospheric pressure.
