methanol \methanol\ n. (Chem.) The simplest alcohol of the paraffin series, CH3.OH; methyl alcohol. Called also wood alcohol. It is used as an antifreeze solvent, as a fuel, and as a denaturant for ethyl alcohol.
Syn: methyl alcohol, wood alcohol, wood spirit.
Methol \Meth"ol\, n. [Gr. ? wine + -ol.] (Chem.) An earlier technical name of methyl alcohol or wood spirit, now called methanol; also, by extension, the class name of any of the series of alcohols of the methane series of which methol proper is the type. See Methyl alcohol, under Methyl.
Methyl \Meth"yl\, n. [See Methylene.] (Chem.) A univalent hydrocarbon radical, CH3-, not existing alone but regarded as an essential residue of methane, and appearing as a component part of many derivatives; as, methyl alcohol, methyl ether, methyl amine, etc. [Formerly written also methule, methyle, etc.]
Methyl alcohol (Chem.), a light, volatile, inflammable liquid, CH3.OH, obtained by the distillation of wood, and hence called wood alcohol or wood spirit; tecnically referred to as methanol; -- called also methol, carbinol, etc.
Methyl amine (Chem.), a colorless, inflammable, alkaline gas, CH3.NH2, having an ammoniacal, fishy odor. It is produced artificially, and also occurs naturally in herring brine and other fishy products. It is regarded as ammonia in which a third of its hydrogen is replaced by methyl, and is a type of the class of substituted ammonias.
Methyl ether (Chem.), a light, volatile ether CH3.O.CH3, obtained by the etherification of methyl alcohol; -- called also methyl oxide or dimethyl ether.
Methyl green. (Chem.) See under Green, n.
Methyl orange. (Chem.) See Helianthin.
Methyl violet (Chem.), an artificial dye, consisting of certain methyl halogen derivatives of rosaniline.

Wiktionary
n. (context organic compound English) The simplest aliphatic alcohol, CH3OH; a colourless, toxic, inflammable liquid, used as a solvent, antifreeze, in the chemical industry, and in the preparation of methylated spirit.
WordNet
n. a light volatile flammable poisonous liquid alcohol; used as an antifreeze and solvent and fuel and as a denaturant for ethyl alcohol [syn: methyl alcohol, wood alcohol, wood spirit]
Wikipedia
Methanol, also known as methyl alcohol, wood alcohol, wood naphtha, methyl hydrate, or wood spirits, is a chemical with the formula C H O H (often abbreviated MeOH). Methanol acquired the name "wood alcohol" because it was once produced chiefly as a byproduct of the destructive distillation of wood. Today, industrial methanol is produced in a catalytic process directly from carbon monoxide, carbon dioxide, and hydrogen.
Methanol is the simplest alcohol, being only a methyl group linked to a hydroxyl group. It is a light, volatile, colorless, flammable liquid with a distinctive odor very similar to that of ethanol (drinking alcohol). However, unlike ethanol, methanol is highly toxic and unfit for consumption. At room temperature, it is a polar liquid, and is used as an antifreeze, solvent, fuel, and as a denaturant for ethanol. It is also used for producing biodiesel via transesterification reaction.
Methanol is produced naturally in the anaerobic metabolism of many varieties of bacteria, and is commonly present in small amounts in the environment. As a result, the atmosphere contains a small amount of methanol vapor. But in only a few days, atmospheric methanol is oxidized by sunlight to produce carbon dioxide and water.
Methanol is also found in abundant quantities in star forming regions of space, and is used in astronomy as a marker for such regions. It is detected through its spectral emission lines.
Methanol burns in oxygen, including open air, forming carbon dioxide and water:
2 CHOH + 3 O → 2 CO + 4 HOMethanol ingested in large quantities is metabolized first to formaldehyde and then to formic acid or formate salts, which are poisonous to the central nervous system and may cause blindness, coma, and death. Because of these toxic properties, methanol is frequently used as a denaturant additive for ethanol manufactured for industrial uses. This addition of methanol exempts industrial ethanol (commonly known as " denatured alcohol" or "methylated spirit") from liquor excise taxation in the US and some other countries.

If a supply of diatomaceous earth does not get discovered before 1633, the safer ethanol process can be set aside in favor of the methanol process.
Biomass can be converted to methane, methanol or gasoline at a fraction of the current cost of oil, coal, or nuclear energy - especially when environmental costs are factored in - and its mandated use would end acid rain, end sulfur-based smog, and reverse the Greenhouse Effect on our planet - right now!
The end result is a very pure form of methanol which can be burned in modified Otto-cycle engines, used as an industrial solvent, or used as the starting point in manufacturing products like bio-diesel fuel.
This biomass conversion process can be adjusted to produce charcoal, methanol and fuel oils to process steam, as well as chemicals important to industry: acetone, ethyl acetate, tar, pitch and creosote.
