Dielectric study of amines: electric dipole moments, solute–solvent interactions, and molecular configuration

Abstract

The electric dipole moments of di-s-butylamine, 2,3-dichloroaniline, N-ethyl-o-toluidine, and N-ethyl-m-toluidine have been determined in benzene and carbon tetrachloride at 30 °C. The effect of solvents on the dipole moments has been examined in the light of Higasi's theory of solute–solvent interaction. The molecular moments have also been calculated by vector-summation methods and the results discussed in terms of the molecular configuration.
