Ethylidene diacetate is an organic compound with the formula (CH3CO2)2CHCH3. A colorless low-melting solid, it once served as a precursor to vinyl acetate.
A major industrial route involves the reaction of acetaldehyde and acetic anhydride in the presence of a ferric chloride catalyst: [1] [2]
It can be converted to the valuable monomer vinyl acetate by thermal elimination of acetic acid:
