Density, Viscosity, and Speed of Sound in the Ternary Mixtures of 2-Ethoxyethanol + <i>N</i>,<i>N</i>-Dimethylformamide + <i>N</i>,<i>N</i>-Dimethylacetamide and 2-Ethoxyethanol + Dimethyl Sulfoxide + <i>N</i>,<i>N</i>-Dimethylacetamide at 308.15 K

Abstract

Experimental values of density, viscosity, and speed of sound of the ternary mixtures of 2-ethoxyethanol (1) + N, N -dimethylformamide (2) + N, N -dimethylacetamide (3) and 2-ethoxyethanol (1) + dimethyl sulfoxide (2) + N, N -dimethylacetamide (3) at 308.15 K and at 18 different concentrations are reported. From the data, the excess volume and the deviations in adiabatic compressibility, viscosity, and speed of sound for the ternary mixtures over the additive values were calculated. The deviations were fitted using the Redlich−Kister equation.
