ABSTRACT

In this work, we report new experimental data on density, q, refractive index, nD, and viscosity, g, of two deep eutectic solvents, N,N-diethylethanol ammonium chloride glycerol (DEACG) and N,N-diethylethanol ammonium chloride ethylene glycol (DEACEG), and their aqueous solutions, over the complete composition range, at temperatures from (298.15 to 343.15) K. Densities and viscosities were measured using the vibrating tube and the falling ball techniques, respectively, while the refractive index at the sodium D line was measured using an automatic refractometer. We aimed to represent the measured properties as a function of temperature and composition, and correlated them using the Redlich Kister-type equation, for density, a polynomial function, for refractive index, and the Vogel Fulcher Tammann (VFT) equation, for viscosity.
