Description and Uses
Ethyl alcohol, also called ethanol, absolute alcohol, or grain alcohol, is a clear, colorless, flammable liquid with a pleasant odor. It is associated primarily with alcoholic beverages, but it has numerous uses in the chemical industry. The word alcohol is derived from the Arabic word al kuhul, which was a fine powder of the element antimony used as a cosmetic. In Medieval times, the word al kuhul came to be associated with the distilled products known as alcohols. The hydroxyl group, -OH, bonded to a carbon, characterizes alcohols. Ethyl is derived from the root of the two-carbon hydrocarbon ethane.
Ethanol is used primarily as a solvent — animportant industrial solvent for resins, lacquers, pharmaceuticals, toilet preparations,and cleaning agents; in the production of rawmaterials for cosmetics, perfumes, drugs, andplasticizers; as an antifreeze; as an automotive fuel additive; and from ancient times, inmaking beverages. Its pathway to the bodysystem is mainly through the consumption ofbeverages. It is formed by the natural fermentation of corn, sugarcane, and other crops.
