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.


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.]

  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.]

    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 5

  4. 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 ( C2H

  5. OH); methyl forms methyl alcohol ( CH3.OH) or wood spirit; amyl forms amyl alcohol ( C5H11.OH) or fusel oil, etc.

Douglas Harper's Etymology Dictionary

"ethyl alcohol," 1900, contracted from ethane, to which it is the corresponding alcohol, + -ol, here indicating alcohol.
