Ethanol, C2H5OH, is manufactured on a large scale for a wide range of uses such as alcoholic drinks, as an industrial solvent and as a raw material for the synthesis of many organic compounds. Ethanol, C2H5OH, is manufactured on a large scale by two methods: • Fermentation, using yeast, of sugars, such as glucose, C6H12O6. C6H12O6(aq) 2C2H5OH(aq) + 2CO2(g) The ethanol is then distilled off. • Hydration of ethene, C2H4, with steam in the presence of an acid catalyst. C2H4(g) + H2O(g) C2H5OH(g) Compare the sustainability of these methods of manufacturing ethanol in terms of: • availability of starting materials and energy requirements; • atom economy. In your answer, you should make clear how the atom economy of the processes links with chemical theory.
