Vinyl acetate is produced from methanol, acetaldehyde and carbon monoxide in a cyclic integrated process wherein methyl acetate is carbonylated to acetic anhydride in a first step, the acetic anhydride is reacted with acetaldehyde to form ethylidene diacetate, the ethylidene diacetate is decomposed into product vinyl acetate which is recovered and co-product acetic acid which is esterified with methanol to provide methyl acetate which is carbonylated in the first step. <IMAGE> |
