Making Alcohols by Fermentation & from Ethene - YouTube
WebbEthanol can be made by hydrating ethene (from oil refining) using steam in the presence of phosphoric acid, which acts as a catalyst. The ethene comes from cracking the distillation products of crude oil. The reaction has a theoretical atom economy of 100%, but some side reactions do occur. . WebbEthanol is manufactured by reacting ethene with steam. The reaction is reversible, and the formation of the ethanol is exothermic. Only 5% of the ethene is converted into ethanol … high rise security bars
