Abstract :Dielectric constants \varepsilon, viscosities h, refractive indices n and densities d have been measured over the entire mole fraction range for the water - methyl, ethyl, n-propyl alcohol binary systems at 298.15 K. From the experimental data excess dielectric constants \varepsilonE, excess viscosities hE and Kirkwood correlation factors gk have been calculated and studied. Their behaviour suggests the existence of intermolecular interactions and plotted curves show that excess dielectric constant and gk values decrease with the increasing of carbon atom number, while excess viscosity increases.
