Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl acetate is moderately toxic when administered through ingestion inhalation and peritoneal injection. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Following ingestion or inhalation vinyl acetate is rapidly metabolized by carboxylesterases to form acetaldehyde and acetic acid. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.
