Thermophysical properties of diethylammonium (acetate + water) mixtures at different temperatures

Density (ρ), speed of sound (w), dynamic viscosity (η), and the electrical conductivity (κ) of the protic ionic liquid (PIL) diethylammonium acetate ([DEA][Ac]), in binary mixtures with water, were measured in order to evaluate how these thermophysical properties are affected by the variation of temperature along a wide composition range. The studied temperature range used for ρ and w was (293.15–323.15) K, for η was (283.15–343.15) K, and for κ...
