Abstract
The relative permittivities of five binary mixtures of ethanol with propan-2-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol and 2-methylpropan-2-ol are reported for twenty-one mole fractions over the entire concentration range at 288.15, 293.15, 298.15, 303.15 and308.15 K. The excess static permittivity, the permittivity temperature coefficient (∂lnε r/∂T) and its excess values were calculated. The excess parameters were fitted to the Redlich–Kister polynomial equation. The results were used in the analysis of hydrogen-bond inter molecular interactions occurring in the alcoholic binary mixtures having different natures of their constituents with varying carbon chain lengths.
