Relative permittivities epsilon are reported for binary liquid mixture
s of acetylene tetrachloride (ATC) with toluene and acetone at 35-degr
ees-C. Measurements of refractive indices have also been made for the
mixtures. The values of the quantity DELTAepsilon, the deviations of t
he relative permittivities of these mixtures from ideality, have been
calculated. The negative values of DELTAepsilon obtained for ATC + tol
uene mixtures may be explained as being due to a decrease in the degre
e of alignment of the molecular dipoles with changing composition of t
he mixture, whereas the positive values of DELTAepsilon obtained for A
TC + acetone mixtures are attributed to the formation of molecular com
plex between acetone and CHCl2CHCl2. The values of the Kirkwood correl
ation parameter g for both sets of mixtures have been calculated using
the relative permittivity data.
