Definition of Alcohols
AlcoholAlcohol 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.
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.
