Dielectric study of binary mixtures of 1-butanol with N, N Dimethylformamide

In the present study, static dielectric constant (ε0) and refractive index (n) have been experimentally determined for binary liquid mixture of 1-Butanol (1-BuOH) with N.N Dimethylformamide (DMF) over varying concentration of both mixture composition in the range (0.0 →1.0) at constant temperature 303 K. Various dielectric parameters namely Kirkwood correlation parameter (g), Kirkwood effective correlation parameter (geff), Kirkwood angular correlation parameter (gF) and Bruggeman parameter (fB) are determined for the binary mixtures. Excess of static dielectric constant (ε0)E and refractive index (n)E are determined. Variations of these parameters against the concentration of constituents are discussed in terms of molecular interaction between the constituent species.
