The present discussion embodies the studies on binary mixtures containing triethylamine with 2-methyl-1-propanol, 2-propanol, and 1-butanol. For this purpose, the density and speed of sound for pure liquids and their binary mixtures were measured within the temperature range 293.15–313.15 K, while viscosity was measured from 298.15 to 308.15 K. Various excess and deviation parameters have been calculated using the measured properties. The calculated parameters reveal the formation of strong intermolecular interactions upon mixture formation. Excess and deviation parameters were fitted to the Redlich–Kister polynomial. The correlation ability of viscosity-related models has also been tested for the studied binary mixtures.
