Oxidation of Olefins-Wacker's Process
Acetaldehyde and vinyl acetate are important industrial intermediates. They may be produced in a variety of ways. But many of these methods suffer major disadvantages. For example, C2H2 is considerably more expensive than C2H4, but the addition of H20 to C2H2 to give CH CHO was found to be somewhat easier than the production of CH3CHO from C2H4.
The oxidation of ethylene to acetaldehyde with platinum group metals has been known since 1894. When ethylene is bubbled into a solution of K2PtCl4, the first product in Zeise's salt, K[PtCl(CH4)]1- Heating this compound in water results ultimately in the formation of acetaldehyde and metallic platinum. Heat [PtCl3 (C2H4)] + H2O In contrast, palladium chloride does not give an isolable intermediate analogous to Zeise's salt, rather, the process moves rapidly to final products in the presence of oxygen
