Acrylic acid
The liquid phase reaction of ethylene with carbon monoxide and oxygen over a Pd2+/Cu2+ catalyst system produces acrylic acid. The yield based on ethylene is about 85%. Reaction conditions are approximately 140°C and 75 atmospheres:
The catalyst is similar to that of the Wacker reaction for ethylene oxidation to acetaldehyde, however, this reaction occurs in presence of carbon monoxide.
