Abstract: The aim of the present work is to obtain effective
permittivity of the reaction mixture during esterification reactions that
can be used in a dynamic simulation environment and analysis the dielectric
properties during the reaction process. Microwave heating serves as an
excellent tool for carrying out such reactions and the multiphysics
simulations need effective permittivity as one of the most important inputs.
In this work, we perform the esterification reaction between ethanol, acetic
acid and butyric acid using a temperature cycle in order to measure the
effective permittivity of the reaction mixture. The obtained result is
fitted using a bivariate function of the concentration of one of the
products of the reaction and temperature of the mixture. The computed
results show good agreement with measured values with maximum errors for the
synthesis reactions of ethyl butyrate and ethyl acetate being 4.94% and
3.68%, respectively.
