The disclosure relates to a process for the preparation of acetic acid. The process comprises reacting a decanter heavy, organic phase of an acetic acid production process with acetic anhydride to convert acetaldehyde in the decanter heavy, organic phase to ethylidene diacetate and separating it from the decanter heavy, organic phase. Ethylidene diacetate can be hydrolyzed to recover acetic acid.
