6.2.1 Manufacture of Ethanol 6.2 Industrial Ethanol 6.2.1 Manufacture of Ethanol LO: I understand how ethanol can be manufactured.

Ethanol for alcoholic drinks is made by : fermentation yeast C6H12O6 C2H5OH + CO2 For industrial purposes, it is cheaper to manufacture ethanol from ethene in an reaction: addition Addition of water is also known as . hydration LO: I understand how ethanol can be manufactured.

LO: I know some uses of ethanol

Ethanol can be made from in crops. carbohydrates So ethanol is a resource. renewable LO: I know some uses of ethanol

LO: I know how ethanol can be used as a feedstock. 6.2.3. Ethanol Feedstock LO: I know how ethanol can be used as a feedstock.

A feedstock is a substance that can be used to make other . products Ethanol can be a feedstock in the manufacture of plastics. Most plastics are made from which currently comes from crude oil. ethene Ethene can also be made from ethanol: aluminium oxide + H2O catalyst LO: I know how ethanol can be used as a feedstock.

This is a reaction: dehydration LO: I know how ethanol can be used as a feedstock.
