At temperatures between 10 and 50°C complex dielectric spectra of mixtures of glycerol and ethanol have been measured in the frequency range from 400kHz to 3GHz. Within the frequency range of measurement the dielectric spectra reveal one dispersion/dielectric loss region, indicating a rather uniform relaxation of both constituents. Exhibiting a continuous but asymmetric relaxation time distribution, the spectra are analyzed in terms of a Davidson–Cole relaxation function to yield the static permittivity, an effective dipole orientation correlation factor, the principal relaxation time, the enthalpy of activation and the Davidson–Cole parameter that measures the width of the relaxation time distribution. These parameters are discussed and compared to those for mixtures of glycerol with water. Effects from the chain-like hydrogen bond structure of the monohydric alcohol, on the one hand, and from the tetrahedral hydrogen network of water, on the other hand, are explored thereby.
