Abstract
Dielectric properties of aluminum stearate in benzene solution were studied. It has been shown that the dielectric loss is due both to the direct-current conductivity and to the relaxation phenomena. Both the dielectric constant and loss decreased with the increase of stearate/aluminum ratio and they varied with aging after dissolution. It was found that the Cole-Cole's circular arc law holds for the complex dielectric constants of aluminum soaps. From the Cole-Cole's circular arc law and also, the method of Williams and Ferry, distribution functions of relaxation time were calculated. The mean relaxation time of mono-soap thus obtained was about the same as that of di-soap, and was greater than that of 1.5-soap. On the basis of these results on dielectric properties, it has been concluded that the mono-soap, as well as the di-soap, forms a kind of aggregate in benzene solution, and the aggregate of mono-soap is probably globular in contrast to the aggregate of di-soap which is believed to be linear.
