Making Ethanol 1: FERMENTATION Warm a solution of sucrose or glucose (sugars) with a yeast catalyst (enzyme) T = 37°C yeast catalyst C6H12O6 2C2H5OH + 2CO2 glucose ethanol • Maximum ≈ 12% (remember: alcohol kills yeast)
Making Ethanol 2: HYDRATION OF ETHENE Reminder: addition reactions of alkenes Very PURE
Dehydrating Ethanol Hot Al2O3 catalyst (Notice that this is the opposite of hydrating ethene) C2H5OH C2H4 + H2O ethene: can test with bromine water
