Investigation of loss factors of some alcohols

The behavior and strength of dielectrics used in electric circuits are investigated with the method of loss factor and Q-factor. The purpose is to calculate the tq delta loss factors of certain liquids. Two liquids of aliphatic structure and one of aromatic structure were dissolved in nonpolar benzene at different concentrations. The results of these measurements are discussed in view of both the structures of the materials and the mechanism involved in the association of their molecules. In addition, the experimental results are compared to the theoretical calculations. The loss tangent was shown to increase linearly with molecule length. At 50% concentration, the loss tangent values of n-butyl alcohol, isopropyl alcohol, and benzyl alcohol are approximately 8*10/sup -3/, 6.5*10/sup -3/, and 2.8*10/sup -3/ respectively. The Q-factor values of n-butyl alcohol, isopropyl alcohol, and benzyl alcohol are 200, 228 and 505 respectively.<>
