Static Permittivities of Isomeric Butanol Mixtures at Temperatures from (288.15 to 308.15) K

Abstract

The relative static permittivities (ε r ) of six binary mixtures of four isomeric butanols are reported for various mole fractions over entire composition range at (288.15, 293.15, 298.15, 303.15, and 308.15) K. The excess values of ε r and the permittivity temperature coefficients (∂lnε r /∂ T ) have been calculated. The excess parameters have been fitted to the Redlich–Kister polynomial equation. The results of the measurements have been used in the analysis of hydrogen-bond interactions between unlike molecules occurring in the alcohol–alcohol mixtures.
