Permittivity of diluted pentanol as a function of temperature

The static dielectric constant of pentanol diluted in decane, cyclohexane and carbon tetrachloride was measured as a function of temperature, at different concentrations. The experimental points were adjusted using the Onsager equation to which a term reducing the molecular interaction was added. Such an empirical equation has already been published for decane solutions. Good agreement between experimental and fitted values of the permittivity was found. The results obtained for the different solvents used are compared and analysed, together with the parameters resulting from the fittings.
