Webster's Dictionary (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]

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]

ethanol \eth"an*ol\ ([e^]th"[a^]n*[add]l), n. (Chem.)
