Received 18 September 2010; revised 4 December 2010; accepted 17 March 2011

Complex dielectric permittivity measurements of 1,2-propanediol–1,4-dioxane mixtures has been carried out at different concentration and in the frequency range of 10 MHz to 20 GHz using time domain reflectometry (TDR). The least squares fit method has been used to obtain the static dielectric constant, relaxation time, and Bruggeman factor for binary mixtures. The Kirkwood–Frohlich theory is applied to compute the dielectric constant for the mixtures. It adequately reproduces the experimental values of static dielectric constants for the 1,2-propanediol–dioxane mixtures. The excess parameters confirm that the heteromolecular hydrogen bonding interactions between 1,2-propanediol and dioxane molecules vary significantly in the mixture. The Bruggeman model for the nonlinear case has been fitted to the experimental dielectric data for mixtures.

Naudojant laikinę reflektometriją, matuota 1,2-propandiolo ir 1,4-dioksano mišinių kompleksinė dielektrinė skvarba 10 MHz – 20 GHz dažnių srityje, esant skirtingoms mišinių koncentracijoms. Mažiausių kvadratų metodu nustatytos dvinarių mišinių statinės dielektrinės konstantos, relaksacijos trukmės ir Brugemano daugikliai. Dielektrinės mišinių konstantos skaičiuotos pagal Kirkvudo ir Friolicho teoriją. Ji tinkamai atkartoja 1,2-propandiolo ir 1,4-dioksano mišinių eksperimentines statinės dielektrinės konstantos vertes. Viršijantieji parametrai patvirtina, kad heteromolekulinės vandenilinio ryšio sąveikos 1,2-propandiolo ir dioksano molekulių mišinyje yra gerokai skirtingos. Mišinių eksperimentiniams dielektriniams duomenims priderintas netiesinio atvejo Brugemano modelis.
