methanol (redirected from Biomethanol)

methanol, methyl alcohol, or wood alcohol, CH₃OH, a colorless, flammable liquid that is miscible with water in all proportions. Methanol is a monohydric alcohol. It melts at −97.8°C; and boils at 67°C;. It reacts with certain acids to form methyl esters. Methanol is a fatal poison. Small internal doses, continued inhalation of the vapor, or prolonged exposure of the skin to the liquid may cause blindness. As a result, commercial use of methanol has sometimes been prohibited. Methanol is used as a solvent for varnishes and lacquers, as an antifreeze, and as a gasoline extender in the production of gasohol. Large amounts of it are used in the synthesis of formaldehyde. Because of its poisonous properties, methanol is also used as a denaturant for ethanol. Methanol is often called wood alcohol because it was once produced chiefly as a byproduct of the destructive distillation of wood. It is now produced synthetically by the direct combination of hydrogen and carbon monoxide gases, heated under pressure in the presence of a catalyst.

 or methyl alcohol or wood alcohol

Simplest of the alcohols, chemical formula CH₃OH. Once produced by destructive distillation of wood, it is now usually made from the methane in natural gas. Methanol is an important industrial material; its derivatives are used in great quantities for making a vast number of compounds, among them many important synthetic dyes, resins, drugs, and perfumes. It is also used in automotive antifreezes, in rocket fuels, and as a solvent. It is flammable and explosive. A clean-burning fuel, it may substitute (at least in part) for gasoline. It is also used for denaturation of ethanol. A violent poison, it causes blindness and eventually death when drunk.
