English → English (gcide) Definition: C5H11OH 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 spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc. [1913 Webster] Amyl alcohol \Am“yl al”co*hol\ (Org. Chem.) Any of eight isomeric liquid alcohols (C5H11.OH), transparent, colorless liquids. It is the hydroxide of amyl. Also called amylic alcohol. The amyl alcohol obtained from fusel oil is mostly isoamyl alcohol (3-methyl-1-butanol or 1-hydroxy-3-methylbutane), with some sec-amyl alcohol (2-methyl-1-butanol or 2-pentanol), and has a characteristic peculiar odor. Other than n-amyl alcohol (also called 1-pentanol) the other isomeric pentanols are not usually refered to as amyl alcohol. The amyl alcohol mixture in fusel oil forms a colorless liquid with a peculiar cough-exciting odor and burning taste. It is used as a source of amyl compounds, such as amyl acetate, amyl nitrite, etc. [Webster 1913 Suppl. +PJC]
