Wacker process is the oxidation of olefins using Pd(II) catalysis and is important industrially method. In Ziegler-Natta polymerisation, monomers are treated with a catalyst, like a mixture of titanium chloride with triethylaluminum.The contact process is a method of producing concentrated sulphuric acid , The catalyst in the process is vanadium oxide. Deacon process is a method of obtaining chlorine gas by passing air and hydrogen chloride gas over a heated catalyst such as copper chloride.
