ABSTRACT OF THE DISCLOSURE An improved liquid phase oxidation process wherein greater amounts of alcohols such as ethyl alcohol can be oxidized to carboxylic acids such as acetic acid by including at least one ketone such as methyl ethyl ketone and at least one aldehyde such as acetaldehyde in the reaction mixture. In a particularly advantageous embodiment, a liquid feed or reaction mixture com- prising from about 40 to 65% ethyl alcohol, about 15 to 50% methyl ethyl ketone, and about 5 to 20% acetaldehyde is oxidized to acetic acid using air, cobalt acetate catalyst, and acetic acid reaction medium.
