It is the most common monohydric alcohol. A volatile colorless transparent liquid with low toxicity; liquid cannot be drunk directly. Have a special aroma and a slightly stimulating spicy taste.

Ethanol is an important organic solvent, widely used in medicine, paint, sanitary products, cosmetics, oil and other methods, accounting for about 50% of the total consumption of ethanol. Ethanol is an important basic chemical raw material. It is used in the manufacture of acetaldehyde, ethylene, ethylamine, ethyl acetate, acetic acid, chloroethane and so on. It also derives many intermediates of medicine, dyestuff, paint, perfume, synthetic rubber, detergent, pesticide and so on. At present, ethanol is used as a chemical product. The use of intermediates is gradually declining, and many products such as acetaldehyde, acetic acid and ethyl ethanol have been replaced by other materials instead of ethanol. 75% of the ethanol solution has strong bactericidal capacity and is a commonly used disinfectant. Specially refined ethanol can also be used for making beverages. Similar to methanol, ethanol can be used as energy source. Some countries have begun to use ethanol alone or blended with gasoline (more than 10%) to save gasoline.
