Abstract: The present invention relates to the field of catalyst technology, and more particularly to the preparation of a supported catalyst and a method of producing ethylidene diacetate using that supported catalyst. The catalyst is represented by the formula M.sub.a X. Compound M includes a group VIII transition metal which catalyzes the formation of ethylidene diacetate, preferably a compound of rhodium or palladium. Carrier X is an organic carrier, preferably selected from the divinylbenzene-polystyrene copolymers, most preferably copolymers having about 1-20% crosslinking. The weight percent of metal M contained in the catalyst is represented by the latter a. The supported heterogenized catalyst results from covalent bonding of the transition metal compound to the organic polymer carrier. Ethylidene diacetate was produced by reacting methyl acetate, iodomethane, carbon monoxide and hydrogen in the presence of this supported catalyst and an accelerator at elevated temperature and pressure.

Abstract: The present invention relates to a process for preparing a catalyst useful in producing ethylidene diacetate and to a process for producing ethylidene diacetate by a continuous process using the catalyst prepared. In the preparation of ethylidene diacetate from carbon monoxide and hydrogen, the conventional preparation method using a homogeneous catalyst system comprising a transition metal catalyst is hampered by difficulty in separating the catalyst from the reaction product after completion of the reaction. The catalyst of the present invention is separated easily from the reaction product. The heterogeneous catalyst of the present invention is prepared by adding a compound of a group VIII metal, preferably rhodium or palladium, to a carrier, preferably .alpha.-alumina, kieselguhr or silica, together with an accelerator containing phosphorus or nitrogen, preferably triphenylphosphine. Using the improved catalyst of the present invention also resulted in increased yield of product over conventional methods.
