Making Ethanol - created from Mind Map

Sugars from plants are converted into ethanol & CO2, the process uses enzymes in yeast (fungi) as a natural catalyst to make the reaction take place. Using plant materials is a renewable resource and makes the fermentation process more sustainable than making ethanol using ethene. On the other hand, a disadvantage is that the land which is used to grow the plant material could be used for growing food.Balanced Equation for the reaction:  C66H12O6 → 2C2H5OH + 2CO2

Fermentation on a small scale. 

Ethanol is made by reacting Ethene, from cracking crude oil, and steam together. The process uses a phosphoric acid catalyst to make the reaction occur quickly. Only ethanol is produced, making the process efficient however ethene is a non-renewable resource which is not sustainable. Equation for the reaction:  ethene + steam → ethanolC2H4 + H2O → C2H5OH

Ethanol is a molecule made of Carbon, Hydrogen and oxygen atoms.

Ethanol is part of the alcohol homologous series, this is flammable, volatile and a colourless liquid. Ethanol has a low Boiling point (lower than water)
