The manufacture of ethanol from ethene - A-Level Chemistry …

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 at each pass through the reactor. By removing the ethanol from the equilibrium mixture and recycling the ethene, it is possible to achieve an overall 95% conversion. Webb15 feb. 2012 · Sugarcane is an important crop for the Brazilian economy and roughly 50% of its production is used to produce ethanol.
