The oxidation of ethanol produces acetic acid. The oxidation of 2-propanol produces acetone. Ethanol or Hydroxyethane. - Ethanol is drinking alcohol. - Prepared by fermentation of carbohydrates or sugars from a variety of plant sources. - Fermentation is done by yeast. - Yeast growth is inhibited by alcohol concentrations of about 14% - Beverages with higer alcohol content are prepated by distillation. Ethanol - The highest concentration of ethanol that can be obtained by simple distillation is 95% - A special type of distillation (azeotropic) by the addition of benzene can produce pure 100% ethanol. - The proof of an alcoholic beverage is twice its alcohol content by volume. Thus 80 proof is 40% alcohol by volume. - Ethanol is absorbed into the bloodstream, metabolized in the liver by enzymes that oxidize it first to acetaldehyde then acetic acid and eventually to carbon dioxide and water which is eliminated through the lungs and kidneys.
