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}); 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: 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.

   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 spirit}; amyl
      forms {amyl alcohol} ({C5H11.OH}) or {fusel oil}, etc.
