Combustion
Ethanol will burn when heated in air or oxygen. This means it can be used as fuel for cars. This fuel contains a mixture of ethanol and petrol. It is available in many countries.
Dehydration
Ethanol can have the elements of water removed from it. This is done by passing ethanol vapour over hot aluminium oxide. This acts as a catalyst for the reaction.
This reaction is sometimes used to manufacture ethene.
