Abstract
Dielectric properties of soybean oil derivatives were measured at freq uency bands from 10(5) to 10(7) Hz at different temperatures. Relaxati on times tau, activation enthalpies Delta H, and entropy changes Delta S for dielectric relaxation were calculated and related to the chemic al changes of the samples. It was found that dielectric properties can be used in differentiating between epoxidized and nonepoxidized oils, and can help in distinguishing these kinds of oils and formoxy-hydrox y derivatives.
