The dielectric constants and losses of 1-propanol and its mixtures with benzene, chlorobenzene, 1,4-dioxane, and pyridine have been measured in the frequency range of 1–0.35 GHz in the temperature range of 10–40 °C. The concentrations of the mixture lie between 1–0.6 mol fractions of the alcohol. The dielectric relaxations of the observed systems in the above frequency range are all of the Debye type. The measured data were used to calculate the activation enthalpy, <I>ΔH</I><SUP>*</SUP>, and the entropy, <I>ΔS</I><SUP>*</SUP>. The dependence of <I>ΔH</I><SUP>*</SUP> and <I>ΔS</I><SUP>*</SUP> upon the concentration differs with the nature of the solvent. Both <I>ΔH</I><SUP>*</SUP> and <I>ΔS</I><SUP>*</SUP> decrease upon the addition of a hydrogenbonding solvent, while they increase slightly upon the addition of a non-hydrogen-bonding solvent. The mechanism of the principal relaxation of 1-propanol is discussed on the basis of these observations.
