Dielectric constants, refractive indexes and polarizations for 1-Alcohol +Heptane mixtures at 298.15 and 308.15 K

New experimental data on dielectric constants, refractive indexes for the binary mixtures of heptane + 1-pentanol, + 1-hexanol, + 1-heptanol, + 1-octanol, 1-decanol and + 1-dodecanol at 298.15 and 308.15 K are reported. The molar and orientation polarizations were calculated for the pure and mixture components. The excess dielectric functions were estimated. The variation of correlation factor and free energy of mixing has been examined over the whole range of 1-alcohol mole fractions for all the binary mixtures. The results are interpreted in terms of molecular interactions.
