Abstract:
Usually, an effective permittivity can be used to describe the molecular polarization of the mixture in the reaction and consequently be used to calculate the transmission and absorption of microwave in the reactant mixtures. In this paper, we propose a method to calculate the effective permittivity of chemical reaction in solution by means of the experimental results. To verify this method, the acetone iodations reaction is employed. The calculated results of complex effective permittivity of the mixtures are in good agreement with the measured results.
