Applications
 
As a fuel:
Methanol can be used as a petrol additive to improve combustion; also research is currently being done on its use as a fuel in its own right.
 
As an industrial feedstock:
Most methanol is used to make various chemicals as formaldehyde, ethanoic acid, and methyl esters of various acids.
