Descripción general

Ethanol is a clear, colorless liquid, which can prepared by fermentation of certain carbohydrates. It is used as a topical disinfectant as it has bactericidal activity. It is the primary ingredient in alcoholic beverages, and is widely used as a solvent and preservative in pharmaceutical preparations. As a solvent of substances intended for human contact or consumption, it is widely used in colorings, scents, flavorings, and medicines. Ethanol has a depressive effect on the central nervous system (CNS), and owing to its psychoactive effects, it is considered a drug. Ethanol has a complex mode of action and affects multiple systems in the brain, most notably it acts as an agonist to the GABA receptors. It is also a gasoline additive and mostly used as an alternative to petroleum as it can reduce CO and CO2 levels during emission when compared to other fossil fuels.

Aplicación

Ethanol has been used as internal standard in GC-MS analysis for the determination of methanol and free glycerol in biodiesel. It may have been used as reference standard in GC analysis for determination of ethanol in beer.
