The reaction of ozone with water solutions of cinnamic and
crotonic acids in a 1 500 mL stirred tank reactor has been studied
under different conditions of pH, temperature and concentration of
reactant. The mass transfer study has been focused from the point
of view of the film theory. The kinetic regime of absorption was
found to be fast. In both systems, secondary reactions of the
products with ozone, as well as the ozone radical decomposition at
pH 7 were detected.
