DES is normally made up of two or more components, all of which are linked together by H-bonds. Abbott and colleagues were the ones who first proposed the concept of DES. As a mixture of two or more components forming an eutectic, the melting point of this eutectic mixture is lower than the individual components of that mixture. The usage of a totally enormous within the freezing point, as well as the capacity to exist in liquid state temperatures is below 150oC. DES, as a new type of green solvent, has certain - reputed properties, such as “high viscosity, high thermal stability and low vapor pressure”. L-lysine-glucose-malonic acid, L-lysine-fructose-malonic acid and L-lysine-fructose-ZnCl2 are three types of ternary deep eutectic solvents (TDESs) that we created in this study. They exist as a clear liquid for more than two weeks at room temperature. Its physical properties, such as “conductivity, density, viscosity pH and thermal properties as the thermal decomposition temperature” of these TDES were studied. The FTIR Spectra of those TDESs have been analyzed to apprehend the interaction of H bonds and three components.

Key words:   Deep eutectic solvent, L-Lysine, Glucose, Fructose, ZnCl2, Malonic acid, FT-IR
