| Abstract: | The relative static
permittivity (dielectric constant) at 1 MHz and high frequency limit
permittivity at wavelength of sodium-D line of the binary mixtures of
2-aminoethanol with 1,4-dioxane or dimethyl sulphoxide over the entire
composition range have been investigated at 30 oC. The concentration
dependent values of excess permittivity and Kirkwood correlation factor of the
binary mixtures indicate the formation of hydrogen bonded molecular
interactions between these unlike molecules, which modify the dipolar ordering
of the self-associated structures of 2-aminoethanol molecules. 2-Aminoethanol
forms 1:1 complexes with dimethyl sulphoxide with increase in number of
effective parallel aligned dipoles, while with 1,4-dioxane it forms 2:1 stable
adducts, which decrease in number of effective parallel aligned dipoles in
their binary mixtures. |
