Methanol

Methanol is the simplest alcohol, and is also known as methyl alcohol. It is colourless, highly flammable, and at typical temperatures and pressures is a liquid. [2] Unlike ethanol, methanol cannot be ingested, as consumption may result in blindness, neurological damage, and damage to the nervous system.[3]

Methanol is used in the production of chemicals, as well as in the manufacturing of polyester fibers, acrylic plastics, and various pharmaceuticals. As well as being a major component in windshield washer fluid, methanol is used as an additive in gasoline.[4] When added to gasoline it serves as an antifreeze and octane booster to give the fuel a better, cleaner burn.

Like many hydrocarbon derivatives, methanol undergoes combustion (see simulation at bottom of page) when combined with heat and oxygen. This reaction releases energy, carbon dioxide, and water.

Combustion Animation

Methanol is used as a combustible fuel. Below is an animation showing the net reaction that occurs during the hydrocarbon combustion of methanol.
