etanolia

Etanolia is a term that may refer to ethanol, the simplest two-carbon alcohol. In modern chemistry, the standard name is ethanol (also known as ethyl alcohol), with the formula C2H6O and the structural formula CH3-CH2-OH. It is a colorless, volatile liquid with a characteristic, mildly sweet odor.

Ethanol is miscible with water and many organic solvents. Its boiling point is 78.37 C. It is produced commercially by the hydration of ethene or by fermentation of sugars by yeast, depending on the intended use. Fermentation yields beverage ethanol, often at several percent by volume, while catalytic hydration produces high-purity ethanol for industrial or fuel applications.

Common uses include as a solvent in laboratories and industry, as a disinfectant and antiseptic, as a fuel or fuel additive (notably in ethanol blends for powering internal combustion engines), and as the principal component of alcoholic beverages. It also serves as a feedstock for the synthesis of other chemicals.

Safety and regulation: Ethanol is flammable and forms explosive mixtures with air. It is metabolized in humans to acetaldehyde and then to acetic acid; excessive consumption can produce intoxication, health risks, and impairment. Handling requires appropriate ventilation and storage away from sources of ignition. Many jurisdictions regulate production, sale, and labeling of beverage-grade and industrial ethanol.

History: Ethanol has been produced by humans for thousands of years through fermentation; modern industrial methods rely on catalytic hydration and fermentation technologies.
