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}.]

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]

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