Preparation and characterization of deep eutectic solvent: physical properties and electrochemical studies

Abstract

A deep eutectic solvent (DES) was prepared by reacting calcium chloride dihydrate with an acetamide at different ratios. The resulting clear colorless DES showed good heat stability ranged between its freezing temperature (-7 ◦C) and decomposition temperature (286.7 ◦C) for (1:7) mole ratio respectively having an ionic conductivity of 0.3 mS/ cm. FT-IR and UV spectra were used to establish its coordination. Other physical properties, such as viscosity, density, and cyclic voltammetry have been measured.
