Industrially, methanol is produced from synthesis gas, a mixture of carbon monoxide and hydrogen derived from coke (the coal, not the soda) or methane. Methanol is used as the fuel in some racing cars, and is being investigated as an renewable alternative to the use of petroleum-based fuels. The main use of methanol, however, is in the manufacture of other chemicals, such as formaldehyde, which is used in the manufacture of plastics, paints, plywood, etc.
