Alcohol \Al"co*hol\ ([acr]l"k[osl]*h[ocr]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.] --Boyle.          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. [bd]Pharmacop[oe]ia,[b8] 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.

Aldehyde \Al"de*hyde\, n. [Abbrev. fr. alcohol dehydrogenatum,       alcohol deprived of its hydrogen.] (Chem.)       A colorless, mobile, and very volatile liquid obtained from       alcohol by certain processes of oxidation.          Note: The aldehydes are intermediate between the alcohols and                acids, and differ from the alcohols in having two less                hydrogen atoms in the molecule, as common aldehyde                (called also {acetic aldehyde} or {ethyl aldehyde}),                {C2H4O}; methyl aldehyde, {CH2O}.
