Hall process reaction
WebIron gives iron pentacarbonyl too, but this reaction is slow. If necessary, it may be separated by distillation. Dicobalt octacarbonyl is also formed in this process, but it decomposes to tetracobalt dodecacarbonyl at the reaction temperature to give a non-volatile solid. Nickel is re-obtained from the nickel carbonyl by one of two processes. WebNote: The carbon anodes need replacement frequently due to the nascent oxygen reaction with the carbon anode.
