Step-by-step solution
The Wacker process is originally referred to the oxidation of ethylene to acetaldehyde by oxygen in water, where the catalyst is tetrachloropalladate ( II ) . In the contact process, Platinum used to be the catalyst for this reaction, however, as it is susceptible to react with arsenic impurities in the sulphur feedstock, the preferred catalyst today is vanadium ( V ) oxide ( V 2 O 5 ) . In the Deacon's process, the reaction takes place at about 400   to   450 o C in the presence of a variety of catal
