What is Ethanol?

Ethanol, also known as ethyl alcohol, is a organic compound with the chemical formula C₂H₅OH. It is a volatile, flammable, colorless liquid that is commonly used as a fuel, solvent, and in alcoholic beverages.

Structure of Ethanol

Ethanol has a simple structure consisting of two carbon atoms, six hydrogen atoms, and one oxygen atom. The carbon atoms are bonded to each other, and each carbon atom is bonded to three hydrogen atoms. The remaining carbon and oxygen atoms are bonded together, forming the characteristic -OH functional group of alcohols.

Properties of Ethanol

• Physical Properties: Ethanol is a volatile, flammable liquid with a boiling point of 78.37°C and a melting point of -114.1°C. It is miscible with water and has a characteristic odor.
• Chemical Properties: Ethanol undergoes various chemical reactions, including combustion to produce carbon dioxide and water, oxidation to form ethanal (acetaldehyde) and then acetic acid, and esterification to form ethyl acetate.

Uses of Ethanol

Ethanol has a wide range of applications, including:

• As a fuel for vehicles, either in pure form (E100) or as a blend with gasoline (E10, E85).
• As a solvent for various substances, such as in the production of pharmaceuticals and perfumes.
• In the manufacturing of alcoholic beverages, including beer, wine, and spirits.
• As a disinfectant and antiseptic in the healthcare industry.
