Dielectric and refractive index measurements for the systems 1-pentanol + octane, or + dibutyl ether or for dibutyl ether + octane at different temperatures

▸ ɛr(T), nD(T) data for 1-pentanol + octane, +dibutylether, and dibutylether + octane are given. ▸ Correlation factors, gk, at 298.15 K are calculated from Kirkwood-Fröhlich equations. ▸ The ether is more active than octane when breaking alkanol self-association. ▸ This is supported by values of molar polarization, ɛr(T) and of gk.
