Abstract: | Relative permittivities are reported for binary liquid mixtures of acetylene tetrachloride (ATC) with toluene and acetone at 35°C. Measurements of refractive indices have also been made for the mixtures. The values of the quantity ![Delta](/content/l150r7053n237833/xxlarge916.gif) , the deviations of the relative permittivities of these mixtures from ideality, have been calculated. The negative values of ![Delta](/content/l150r7053n237833/xxlarge916.gif) obtained for ATC+ toluene mixtures may be explained as being due to a decrease in the degree of alignment of the molecular dipoles with changing composition of the mixture, whereas the positive values of ![Delta](/content/l150r7053n237833/xxlarge916.gif) obtained for ATC+acetone mixtures are attributed to the formation of molecular complex between acetone and CHCl2CHCl2. The values of the Kirkwood correlation parameter g for both sets of mixtures have been calculated using the relative permittivity data. |
