Acetone, methyl ethylketone, methyl isopropylketone and toluene were oxidized separately in the liquid phase by oxygen at 140°C, under 15 atm partial pressure of oxygen with 1 wt % di‐ ter‐ butylperoxide. The main product is acetic acid. Acetone is much less reactive than the other two ketones. Cooxidations of binary mixtures composed of a ketone and toluene were performed under the same experimental conditions. In these cooxidation systems, the three ketones have similar reactivities. The discrepancy between the relative reactivities of the ketones oxidized alone or with toluene is interpreted by the theory of the branched chain oxidations, and indicates the great influence of the chain branching coefficients and the stability of the free peroxy radicals on the total rate of oxidation of the ketones.
