چکیده:

Relative permittivity measurements were made on binary mixtures of (1,2-butandiol + 1,4-dioxane) for various concentrations at T = 298.2 K, 308.2 K and 318.2 K. The molecular dipole moments were determined using Guggenheim-Debye method in the temperature range of (298.2 to 318.2) K. The variations of effective dipole moment and correlation factor, g, with the mole fraction in these materials were investigated using Kirkwood-Frohlich equation. The pure compounds showed a negative and small temperature coefficient of effective dipole moment.
