Ethanol C2H6O. Often C2H5OH.

·        Ethanol can be made using fermentation of sugar from plants using yeast. Enzymes in yeast convert sugars into ethanol and carbon dioxide.

o   Uses renewable resources but produces dilute form of ethanol – fractional distillation has to be used to separate and form pure ethanol.

·        Made by hydration of ethene

o   Ethene reacted with steam at high temps I presence of catalyst. Ethene obtained from crude oil by cracking.

o   Uses non-renewable resources but produces pure ethanol and requires high temps.
