Densities and viscosities of binary mixtures consisting of tetrahydrofuran (THF), 1,3-dioxolane (1,3-DO) and 1,4-dioxane (1,4-DO) with N,N--dimethylformamide (DMF) over the entire range of composition were measured at the temperatures 298.15, 308.15 and 318.15 K and at atmospheric pressure. The ultrasonic speeds of sound of these binary mixtures were measured at ambient temperature and atmospheric pressure (T = 298.15 K and p = = 1.01×10 5 Pa). The various experimental data were utilized to
