Reaction Steps
Into an autoclave were charged 135 g of acetic anhydride, 15 g of methyl iodide and 4.5 g of palladium (5%) supported on barium sulfate (Kawaken Finechemical Co.). The reaction was effected for 90 minutes in the same way as in Example 9. GC analysis showed that 0.415 g of vinyl acetate and 14.0 g of ethylidene diacetate were formed with considerable amount of acetic acid.
