Yeasts eat sugars in anaerobic conditions and produce alcohols as a waste product.
Ethanol, methanol and proponal are all alcohol based fuels. These fuels are good for the environment because they are slower burning fuels, which make it easier to gain energy from. These fuels also do not need fossil fuels to be created, they can be derived from water and carbon dioxide.
all fuels are better
some of the low cost fuels are bio ethanol,bio methanol,cellulose bio mass etc.
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
You can drink ethanol. If you drink methanol, even a small amount, you will go blind.
Methanol is CH3OH while ethanol is C2H5OH. The difference is CH2.
Methanol
Methanol is CH3OH, ethanol is CH3CH2OH. Both are alcohols, ethanol has one carbon more (or a CH2 group more) and is less polar than methanol. Also ethanol has higher boiling point than methanol.
Methanol and ethanol mix together well in part because they both have a low boiling point. Methanol and ethanol mixed together also metabolizes well.
ethanol is used in alcohol
Methanol have single carbon atom compound and ethanol have two carbon atoms.
The word sought may be the adjective "emotional" (displaying emotions). Similarly-spelled terms are ethanol and methanol, alcohols used mainly as fuels.
