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

   also methule, methyle, etc.]
   [1913 Webster]

   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.

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.]
      [1913 Webster]

   2. The fluid essence or pure spirit obtained by distillation.
      [Obs.] --Boyle.
      [1913 Webster]

   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.]
         [1913 Webster +PJC]

   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
         54.5 per cent of water.
         [1913 Webster]

   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 (C2H5.OH); methyl
      forms methyl alcohol (CH3.OH) or wood alcohol; amyl
      forms amyl alcohol (C5H11.OH) or fusel oil, etc.
      [1913 Webster]

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.
   [1913 Webster]
