Resumen:
The dependence on temperature of the permittivity and conductivity of mixtures ofFatty Acid Methyl Esters (FAME) was determined between 300K and 343K, in the frequency range from 20Hz to 2MHz. Samples were made from oil of sunflower, corn, grape, chia, canola, jatropha, coconut and cottonseed. Permittivity fits very well to a linear function of temperature, the fitting parameters falling within a narrow range for all samples. Conductivity follows an Arrhenius dependence with activation energies between 0.202eV and 0.252eV. The results show that measurments of electrical properties, succesfully used for the characterization of FAME from soybean oil, as reported in previous works, can also be employed in FAME obtained from different feedstocks. This generalization is relevant for laboratory and industrial characterization and quality control, and also for the application of ?on line? measurements in automated production systems.
