With rate constants (ki -values) available, the
mathematical model can be used to predict the reaction yield values
under the same temperature condition. CCRD experiments performed under
similar ultrasound power as which the kinetics were obtained were
selected so the model could be applied with different initial
conditions. The ultrasound power affects the temperature of the system
and, thus, the equilibrium. Hence, the values of the FFA yield obtained
experimentally and predicted by the model are shown in Table 3 .
The model was able to predict FFA yield under the conditions evaluated
with an average deviation of 17.32%. Since the data used for this
validation was not obtained in the exact conditions of ultrasound power,
a variation was expected. The applied model was, therefore, satisfactory
to explain the reaction mechanisms and can be useful for
phenomenological studies and process optimization.
