Vinyl acetate monomer

The major use of acetic acid is for the production of vinyl acetate monomer (VAM). This application consumes approximately 40% to 45% of the world’s production of acetic acid. The reaction is of ethylene and acetic acid with oxygen over a palladium catalyst.
2 H3C-COOH + 2 C2H4 + O2 → 2 H3C-CO-O-CH=CH2 + 2 H2O
Vinyl acetate can be polymerized to polyvinyl acetate or to other polymers, which are applied in paints and adhesives.
