Resumen: In this work, a physicochemical characterization of the Deep Eutectic Solvent, reline (formed by chloline chloride and urea in a molar ratio 1:2) and one of its aqueous mixtures (xreline = 0.645) has been made at atmospheric pressure (0.1 MPa) in a wide range of temperatures (288.15–338.15) K for reline and (278.15–338.15) K for the aqueous mixture. The measured properties were: density, speed of sound, refractive index, isobaric molar heat capacity, surface tension, kinematic and dynamic viscosity and electrical conductivity. Additionally, from these experimental results, some derivate properties such as isobaric thermal expansibility, isentropic compressibility, molar refraction, free volume and entropy and enthalpy of surface formation have been obtained. Taking into account the observed behaviour the introduction of water, at the considered composition, only modify drastically the dynamic viscosity and electrical conductivity.
