Abstract
An improved process for the liquid phase oxidation of methyl ethyl ketone to acetic acid wherein increased carbon efficiencies are achieved by including formic acid and/or at least one formic acid-producing compound such as methyl formate in the reaction mixture. In a particularly advantageous embodiment, a liquid reaction feed mixture consisting essentially of from above about 50 to 90 percent methyl ethyl ketone and from about 10 up to about 50 percent of formic acid and/or the formic acid-producing compound is oxidized to acetic acid using air, cobalt acetate catalyst, and acetic acid reaction medium.
