Ethanol is an organic compound with a simple structure of CH3CH2OH or C2H5OH and a molecular formula of C2H6O, commonly known as alcohol.
Ethanol at room temperature and pressure is a volatile colorless transparent liquid, low toxicity, pure liquid can not be directly drunk. The aqueous solution of ethanol has a wine aroma, and slightly pungent, sweet taste. Ethanol is flammable and its vapors can form explosive mixtures with air. Ethanol is miscible with water at any ratio and miscible with chloroform, ether, methanol, acetone and most other organic solvents.
Ethanol can be used to make acetic acid, beverage, essence, dye, fuel, etc., commonly used in medical treatment volume fraction of 70%~75% ethanol as a disinfectant. Ethanol has a wide range of uses in chemical industry, medical and health care, food industry, agricultural production and other fields.

Application
1，Medical supplies
Ninety-five percent alcohol can be used to wipe UV lamps. This alcohol is commonly used in hospitals, but in homes it is used only to clean camera lenses. 70% to 75% alcohol can be used for disinfection. If the alcohol concentration is too high, it will form a protective film on the surface of the bacteria, preventing it from entering the body of the bacteria, and it is difficult to completely kill the bacteria. If the alcohol concentration is too low, although it can enter the bacteria, but it can not coagulate the proteins in the body, nor can it completely kill the bacteria. So 75% alcohol is the best. 40 to 50 percent alcohol can be used to prevent bedsores. Long-term bedridden patient's back, waist, hip because of long-term pressure can cause bedsores, such as massage a little 40% ~ 50% of the alcohol into the hand, evenly massage the patient under pressure, can achieve the purpose of promoting local blood circulation, prevent the formation of bedsores. 25% ~ 50% alcohol can be used for physical antipyretic. Patients with high fever can use it to wipe the body, to achieve the purpose of cooling. Wipe the skin with alcohol, can make the patient's skin blood vessel expansion, increase the skin heat dissipation ability, alcohol evaporation heat absorption, so that the patient's body surface temperature, symptoms relief. It should be noted that the alcohol concentration should not be too high, otherwise it may irritate the skin and absorb a lot of moisture from the epidermis.
2，Food and beverage
Ethanol is the main component of wine, and the content is related to the type of wine. It should be noted that the ethanol in drinking wine is not added to the ethanol, but the ethanol obtained by microbial fermentation. According to the different types of microorganisms used, there will be acetic acid or sugar and other related substances.
Ethanol can also be used to make acetic acid, beverages, baked goods, candies, ice cream, sauces and so on. 3，Organic raw materials
Ethanol is also a basic organic chemical raw material, which can be used to produce acetaldehyde, acetic acid, ether, ethyl acetate, ethylamine and other chemical raw materials, as well as solvents, dyes, coatings, flavors, pesticides, pharmaceuticals, rubber, plastics, man-made fibers, detergents and other products.
4，Organic solvent
Ethanol can be miscible with water and most organic solvents, and is widely used as a solvent for organic chemical reactions and adhesives, nitro spray paint, varnish, cosmetics, ink, paint remover, etc.
Ethanol is also a common solvent in liquid preparations, used in mixtures, tinctures, and injections. The polarity of ethanol is less than that of water, and it can dissolve medium polarity, weak polarity and non-polar components in traditional Chinese medicine, such as alkaloids and their salts, glycosides, volatile oils, resins, tannins, organic acids and lipophilic pigments. In traditional Chinese medicine, alcohol is often used to make medicinal wine, and Chinese medicine is sent to make the effect of medicine more effective; It also uses its anticorrosive effect for storage and storage of items.
Because the pigment in chloroplast can be dissolved in absolute ethanol, absolute ethanol is commonly used to extract the pigment in chloroplast in biology. 5，Motor vehicle fuel
Ethanol can be used as a vehicle fuel alone or blended with gasoline as a blend fuel.
Adding 5%~20% fuel ethanol to gasoline to make ethanol gasoline can reduce the pollution of air from automobile exhaust. In addition, ethanol can be added to gasoline as an antiknock agent to replace tetraethyl lead.
