ethyl alcohol
(gcide) | 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] |
ethyl alcohol
(gcide) | ethanol \eth"an*ol\ ([e^]th"[a^]n*[add]l), n. (Chem.)
The organic compound C2H5.OH, the common alcohol which is
the intoxicating agent in beer, wine, and other fermented and
distilled liquors; called also ethyl alcohol. It is used
pure or denatured as a solvent or in medicines and colognes
and cleaning solutions, or mixed in gasoline as a fuel for
automobiles, and as a rocket fuel (as in the V-2 rocket).
Syn: ethyl alcohol, fermentation alcohol, grain alcohol.

Methyl alcohol
(gcide) | 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.]
[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.
