Method for the preparation of an alkenyl carboxylate.

摘要

An alkenyl carboxylate having a higher value than, for example, vinyl acetate can be prepared by the ester-exchange reaction between a corresponding carboxylic acid and vinyl acetate in the presence of a catalyst system comprising (a) a palladium compound, (b) copper bromide or a combination of a copper compound other than copper bromide and an inorganic bromine compound and (c) a lithium compound selected from lithium carboxylates, lithium carbonate, lithium hydrogencarbonate and lithium hydroxide.
