Fluid structure in amines could be readily studied by dielectric measuremen
ts by virtue of the influence of local order and the overall dipole moment.
The short range interaction between permanent dipoles could be described b
y the Kirkwood-Frohlich correlation factor. In dilute solutions of amines w
ith inert solvents, the interaction between the solute species among themse
lves may be given by a modified form of the correlation factor (g') by taki
ng the solute-solvent and solvent-solvent interaction. Dielectric constant
of the binary mixtures of monoethanolamine and diethanolamine in 1,4 dioxan
and triethylenetetramine and cyclohexylamine in. benzene were measured at
298, 308 and 318 K. The values of Kirkwood-Frohlich correlation factor (g')
were determined at the temperatures mentioned above. The results are inter
preted in the light of the theory. The presence of alpha and beta multimers
in the above systems was identified.
