A study was made of the oxidation rate of methyl ethyl ketone with ozone in aqueous solutions at a low oxygen content in the reaction mixture.
In the absence of acid the oxidation proceeds by a radical chain mechanism, with chain termination in the reaction\(\dot R + O_2 \to R\dot O_2 \), and chain propagation in the reaction of the R radicals with ozone.
In the presence of HNO3, ozone reacts with the enol form of methyl ethyl ketone by the nonradical path.
