It is a kind of alcohol, which is the main component of wine, so it is also called alcohol. The chemical formula of alcohol is C2H6O(CH3CH2OH or C2H5OH) or EtOH, which is a saturated monohydric alcohol with only one hydroxyl group and is an isomer with methyl ether.

Ethanol is a flammable, volatile, colorless and transparent liquid at normal temperature and pressure, and its aqueous solution has bouquet flavor and slight irritation. It smells of wine, pungent and slightly sweet. The density of ethanol liquid is 0.789 g/cm3 (20 degrees Celsius).

The density of ethanol gas is 1.59kg/m3, the boiling point is 78.3℃, and the melting point is-1 14. 1℃. It is flammable, and its steam can form an explosive mixture with air, which can be mixed with water in any proportion. It is miscible with most organic solvents such as chloroform, ether, methanol and acetone, and its relative density is (D 15.56) 0.85438+06.

Ethanol is widely used. It can be used to make acetic acid, beverages, spices, dyes, fuels and so on. Ethanol with a volume fraction of 70%-75% is also a commonly used disinfectant in medical treatment, which is widely used in national defense industry, medical and health care, organic synthesis, food industry and industrial and agricultural production.
