Abstract
Dielectric properties of mixtures of 1-alcohols (ethanol, 1-butanol and 1-hexanol) and tetraethyl orthosilicate (TEOS) were determined by means of the time domain method (TDS). To all spectra were fitted a model function containing a sum of three debye relaxation terms with fixed τ2 and τ3. Initially, to 2–3 mole%, TEOS did not influence static permittivity nor main relaxation time of the alcohol. For higher concentrations there is a linear decrease in both these parameters. Qualitatively the effects of TEOS are comparable with those of a nonpolar hydrocarbon on the alcohol structure.
