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.
