Methyl alcohol, or wood alcohol, CH 3 OH, 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
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.
