Thermophysical characterization of choline chloride: Resorcinol and its mixtures with water

• A deep eutectic solvent formed by choline chloride and resorcinol (mole ratio 1:2) is presented. comprehensive study of the thermophysical properties this DES has been performed. Two their aqueous mixtures have also thermophysically characterized. All these systems characterized NRM techniques. The solvents increased in recent years. This because great solubility ability lower toxicity than usual organic solvents. In work, mole 1:2 its with water, e.g., chloride:resorcinol:water 1:2:1.05 (water mass fraction = 0.05) 1:2:2.22 0.1), studied. Several physicochemical (density, speed sound, isentropic compressibility, refractive index, surface tension, isobaric molar heat capacity, viscosity, electrical conductivity) obtained analysed at atmospheric pressure range 283.15–338.15 K. starting temperature for sound measurements was 308.15 effects water inclusion evaluated. results shown a linear correlation between density, tension capacity temperature. Additionally, viscosity conductivity data can be adjusted using Vogel-Fulcher-Tammann equation. Finally, to check how were modified. These modifications had greater on transport properties, conductivity.
