ABSTRACT:
Alkylidene diesters such as ethylidene diacetate are produced by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound and a halogen component at a temperature in the range from 125.degree. to 300.degree. C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm.sup.2. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.
