What is "ch3oh"

Carbinol \Car"bi*nol\, n. [Carbin (Kolbe's name for the radical) + -ol.] (Chem.) Methyl alcohol, CH3OH; -- also, by extension, any one in the homologous series of paraffine alcohols of which methyl alcohol is the type.

Alcohol \Al"co*hol\ ([a^]l"k[-o]*h[o^]l), n. [Cf. F. alcool, formerly written alcohol, Sp. alcohol alcohol, antimony, galena, OSp. alcofol; all fr. Ar. al-kohl a powder of antimony or galena, to paint the eyebrows with. The name was afterwards applied, on account of the fineness of this powder, to highly rectified spirits, a signification unknown in Arabia. The Sp. word has both meanings. Cf. Alquifou.]

1. An impalpable powder. [Obs.]

2. The fluid essence or pure spirit obtained by distillation. [Obs.]
   --Boyle.

3. Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol or ethanol, CH3.CH2.OH); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation.

   Note: [The ferementation is usually carried out by addition of brewer's yeast, Saccharomyces cerevisiae to an aqueous solution containing carbohydrates.]

   Note: As used in the U. S. ``Pharmacop[oe]ia,'' alcohol contains 91 per cent by weight of ethyl alcohol and 9 per cent of water; and diluted alcohol (proof spirit) contains 45.5 per cent by weight of ethyl alcohol and 5

4. 5 per cent of water.

   4. (Organic Chem.) A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol ( C2H

5. OH); methyl forms methyl alcohol ( CH3.OH) or wood spirit; amyl forms amyl alcohol ( C5H11.OH) or fusel oil, etc.

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.

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.
