Creation of Ethanol

HideShow resource information

Fermentation

-Uses Renewable resources (sugar cane)
-Batch Process
- Very slow rate of reaction, takes several days for each batch
- Product is dilute ethanol that would need further processing if pure ethanol is needed.
-Low temperatures are required for these reaction conditions.

Hydration of Ethene

-Uses Non-Renewable resources (crude oil)
- Continuous process
- Fast rate of reaction
- Produces pure ethanol
- High temperatures and pressures are required for reaction conditions. (More expensive.)

Reactions of Ethanol

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.
