Topic: Ethanol or ethyl alcohol


  
  Ethanol - Wikipedia, the free encyclopedia
Ethanol, also known as ethyl alcohol or grain alcohol, is a flammable, tasteless, colorless, mildly toxic chemical compound with a distinctive odor, and is the alcohol found in alcoholic beverages.
Ethyl nitrite, prepared from the reaction of ethanol with sodium nitrite and sulfuric acid, was formerly a widely-used diuretic.
The ethanol content of a beverage is usually measured in terms of the volume fraction of ethanol in the beverage, expressed either as a percentage or in alcoholic proof units.

 HighBeam Encyclopedia - ethanol
Ethanol forms a constant-boiling mixture, or azeotrope, with water that contains 95% ethanol and 5% water and that boils at 78.15°C; since the boiling point of this binary azeotrope is below that of pure ethanol, absolute ethanol cannot be obtained by simple distillation.
Ethanol is used extensively as a solvent in the manufacture of varnishes and perfumes; as a preservative for biological specimens; in the preparation of essences and flavorings; in many medicines and drugs; as a disinfectant and in tinctures (e.g., tincture of iodine); and as a fuel and gasoline additive (see gasohol).
Denatured, or industrial, alcohol is ethanol to which poisonous or nauseating substances have been added to prevent its use as a beverage; a beverage tax is not charged on such alcohol, so its cost is quite low.

This ratio is chosen because ethanol and water form a binary azeotrope at this ratio with a boiling point of 78.15 degrees C. [Celsius].
Ethanol is seldom produced commercially (except for booze) by distillation.
Thus most commercial ethanol is intentionally diluted with water to the 95:5 concentration because it represents the composition with the lowest boiling point and hence the most stable composition for use in a normal atmospheric environment.

Completely Denatured Alcohol may not be used in the manufacture of preparations or products for internal human use or consumption where any of the alcohol or the denaturants used in that alcohol remain in the finished product.

An alcohol is generally classified by the number of hydroxyl groups in its molecule.
The monohydric alcohols are further classified as primary, secondary, or tertiary according to the number of carbon atoms bonded to the carbon atom to which the hydroxyl group is bonded.
Alcohols are generally less volatile, have higher melting points, and are more soluble in water than the corresponding hydrocarbons (in which the -OH group is replaced with hydrogen).
