Methanol or methyl alcohol is the simplest alcohol, with a chemical formula of CH3-OH. It is used in the production of methyl tert-butyl ether (MTBE), a gasoline additive, to make biodiesel and as a solvent, antifreeze and feedstock for certain plastics. A byproduct in earlier times of the destructive distillation of wood, hence its old name "wood alcohol," methanol is now synthesized from natural gas.
