چکیده انگلیسی
The aim of this work is the study of the electromagnetic behaviour of polar-non polar dielectric mixtures of the type alcohol + n-alkane from primary alcohols 1-pentanol, 1-hexanol, and 1-heptanol, by means of the determination of the complex dielectric permittivity É* by TDR in the range DC-5 GHz at room temperature. The method allows to determine the magnitudes of the dielectric process, static dielectric constant És and relaxation time Ï0, at concentrations between 0.05 and 0.80 mole fractions of alcohol. The molecular interaction in these systems is interpreted by means of the behaviour of the relaxation time and the excess dielectric constant (ÎÉs)E according to the mixture models of Wiener and Lichtenecker. These dielectric relaxation results have been compared with other equilibrium properties of this type of alcohol + alkane or + cycloalkane mixtures.
