✦ Synopsis

The static permittivity has been investigated for the ternary mixtures of 1,6hexanediol/n-dodecanol/heptane, 1,2-ethanediol/n-dodecanol/heptane, and 1,6-hexanediol/nhexanol/heptane. In addition, the static properties of pure n-hexanol and binary solutions of n-hexanol, cyclohexanol and n-heptanol in n-heptane have been studied together with the binary mixture hexanediol/hexanol. The results are discussed. Broadband dielectric relaxation spectra (at 20 to 40 "C) are reported for the three ternary systems. The concentration of the polar substances ranges from alcohol mole fraction z = 0.1 to 1. The dependence of relaxation parameters on concentration and temperature of the ternary mixtures is discussed.
