WHAT DO WE MEAN WHEN WE SAY ALCOHOL?
• Alcohol – any organic compound containing OH-
• Alcohol is used in fuel, paint, disinfectants, plastics and even beverages.
• Alcohol usually refers to either ethanol or methanol, the most commonly used members of the alcohol family.

METHANOL
CH3OH
• Methanol is extremely toxic to humans and also very flammable.
• If ingested, it causes hypoxia (lack of oxygen) in the cells.
• It is used as a denaturant for other alcohols.
• Also used as an additive for gasoline.

DENATURED ALCOHOL
• Alcohol not intended for human consumption is denatured.
• Denaturation is the process through which alcohol is rendered unfit for human consumption for tax reasons.
• A toxic or extremely undesirable tasting liquid is added to make it impossible for people to drink.
• Ethanol is denatured before it is used for chemical purposes.

ETHANOL
C2 H5OH
• Ethanol is the most common alcohol, found in beverages, paints, adhesives, and nail polish remover.
• Diesel cars can run on 100% ethanol and all cars can run on a combination of gasoline and ethanol.

ISOPROPYL ALCOHOL
C3H8O
• Structural isomer of propyl alcohol.
• Simplest of the secondary alcohols, which have the OH- attached to the second Carbon.
• Known mostly as “rubbing alcohol”.

FERMENTATION/DISTILLATION
• Ethyl alcohol is produced through fermentation of a grain, typically corn.
• Methanol was produced through distillation of wood.
• Methanol is now produced using water and a nickel catalyst according to the equation CH4 + H20 CO+ 3H2.
