Dielectric properties of 1‐butanol and of mixtures of 1‐butanol with hexane and with tetrachloromethane

AbstractThe dielectric properties of 1‐butanol and of mixtures of 1‐butanol with hexane and with tetrachloromethane have been determined in the frequency range between 10KHz and 40GHz at temperatures from 249.0°K to 288.2°K.The Kirkwood correlation factor g computed from the dielectric constant is greater than 1 for 1‐butanol and for most mixtures. This is explained by an excess of the linear multimers with a high dipole moment formed by the association of molecules through hydrogen bonding. The greater part of the dispersion region is to be described by a relaxation process characterized with one relaxation time. The agreement between the dependence on concentration of the relaxation time and the correlation factor confirms the suggestion that this relaxation process is to be ascribed to the linear multimers. Linear multimers are present even in the dilute solution.
