Abstract:

The temperature dependence of the dielectric relaxation time was investigated from -5 to 50 C for ethanol-cyclohexane solutions from 1.0 to 0.25 mole fraction ethanol. T e previously observed maximum in the relaxation time around equimolar composition is explained by a H-bonded switching mechanism. Measurements of dielectric relaxation from 5 to 50 C were carried out on 3 isomeric butanediols which differ in the separation of the two OH groups along the carbon skeleton. The differences in relaxation times among the 3 isomers can be explained by the switching mechanism suggested by the results for the ethanol-cyclohexane solutions. The dielectric relaxation times of n-butanol from 5 to 50 C were determined. The chain-length dependence of the dielectric relaxation time of the normal aliphatic alcohols is discussed in terms of the proposed mechanism. Author
