Static Dielectric Constants, Densities, Refractive Indices and Related Properties of Binary Mixtures at Various Temperatures Under Atmospheric Pressure

Experimental dielectric constants at (293.15, 298.15, 303.15) K, densities and refractive indices 293.15 K are reported for water- ethanol n-butanol binary mixture systems over the entire volume fraction range atmospheric pressure. From experimental data, excess constant, effective Kirkwood correlation factor, Bruggeman factor from density index data various parameters their properties like density, index, molar polarization, were estimated in study. The static constant of studied mixtures decreases with increase temperature solutes. values decreasing increasing water. Excess volumes negative shows presence intermolecular interaction hydrogen bonding both mixtures.
