Abstract
Deep eutectic solvent is abbreviated as DES. Deep Eutectic Solvents are types of environmentally green solvents. As a new type of solvents, DES has an extremely large number of applications. Even though the problems associated with conventional volatile organic solvents are well studied, the usage of green and bio-renewable solvents still remains a never-ending challenge. DES have been studied in a variety of applications, different process and metal-catalyzed organic reactions. In recent years, low melting mixtures consisting of carbohydrates, urea, and inorganic salts have been introduced as new alternative sustainable solvents for organic transformations. In the present work, amino acid Glycine was added to Citric acid and Malonic acid and Tartaric acid was added to Ethylene glycol to form binary deep eutectic solvents. The physical properties such as conductivity, density, viscosity and pH were measured and analyzed as function of temperature in the range of 300–350 K. The thermal properties such as thermal decomposition temperature, molar heat capacity and glass transition temperature were measured for these deep eutectic solvents. These DESs were characterized by FTIR spectra to evaluate the formation of hydrogen bond.
