Ethanol

Ethanol is used in alcoholic drinks, disinfectants, perfumes, aftershaves and fuel.

The first way of creating ethanol is by fermentation and the second is by reacting ethene and steam.

Fermentation:

Needs sugars
Needs yeast
Needs water
All these combine together to form ethanol and carbon dioxide
Much cheaper
Low temperatures
Produces CO2
Lots of land for the crops that produce the sugar

Reacting ethene with steam:

Ethene and steam are reacted together with a catalyst at high temperatures to create ethanol.
Ethene + Water -> Water
Hydration
No CO2 produced
Quicker
Requires less people
Expensive
Using crude oil (Non renewable)
