Abstract

This chapter contains dielectric relaxation parameters of binary systems containing monohydroxyl alcohol with ester using the time domain reflectometry technique at different temperatures. The relaxation in this system can be described by a single relaxation time using the Debye model. The dielectric parameters, viz., static permittivity, relaxation time, Kirkwood correlation factor, excess permittivity, excess inverse relaxation time, activation energy, and Bruggeman factor, have also been determined for methyl acetate–alcohol, ethyl acetate–alcohol, and butyl acetate–alcohol binary systems. The values of the static dielectric constant and relaxation time increase with an increase in the percentage of alcohol in methyl acetate, ethyl acetate, and butyl acetate. This chapter provides important information about the molecular interaction between ester and alcohol at microwave frequency.
