What does alcohol do and what does alcohol do

Promote blood circulation, lead drugs to the upside, a small amount of blood activation, a large amount of anesthesia, and commonly used excipients.

Disinfection, rubbing the body when there is a fever, and heat dissipation.

There are six main uses for the effects of alcohol:

1. Industrial raw materials.

1. a solvent; organic synthesis; crystallization of various compounds; Detergent; Extractant;

2. Edible alcohol can be blended with liquor; used as a binder; nitro spray paint; Solvents for varnishes, cosmetics, inks, paint removers, etc., as well as raw materials for the manufacture of pesticides, pharmaceuticals, rubber, plastics, man-made fibers, detergents, etc., as well as antifreeze, fuels, disinfectants, etc.

The ethanol solution is commonly used for medical disinfection.

2. Disinfection supplies.

1. Alcohol above volume fraction is called anhydrous alcohol. Uses in biology: The pigments in chloroplasts can be dissolved in the organic solvent absolute ethanol (or acetone), so the pigments in chloroplasts can be extracted with absolute ethanol.

75% alcohol is used for disinfection. This is because too much alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, making it difficult to kill the bacteria completely. If the alcohol concentration is too low, it can enter the bacteria, but it cannot coagulate the proteins in the body, and it cannot completely kill the bacteria.

Of these, 75% of alcohol disinfection is the best.

50% alcohol can be used to reduce fever physically. Patients with high fever can use it to wipe their bodies to achieve the purpose of cooling down. Because wiping with alcohol can dilate the patient's blood vessels, increase the heat dissipation capacity, and the alcohol evaporates and absorbs heat, so that the patient's body surface temperature is reduced and the symptoms are relieved.

3. Beverage products.

Ethanol is the main ingredient of wine (the content depends on the type of wine).

The degree of liquor indicates the percentage of alcohol contained in the volume of the liquor (the proof is commonly used in Western countries to indicate the alcohol content), which is usually expressed in the volume ratio of 20, such as the 50-degree liquor, which means that in 100 ml of wine, it contains 50 ml of ethanol (20). In the case of beer, the concentration of the wort is the raw material for beer production, and in the case of beer at 12 degrees, for example, the concentration of the wort extract before fermentation is 12% (weight ratio). The extract in wort is a mixture of several components, with maltose as the main component.

The concentration of ethanol in beer is generally less than 10%.

Fourth, organic raw materials.

Ethanol can be used to prepare chemical raw materials such as acetaldehyde, ether, ethyl acetate, and ethylamine, as well as raw materials for the preparation of dyes, coatings, detergents and other products.

5. Automobile fuel.

As early as the 19th century, modern bioenergy ethanol appeared. In 1902, the Deutz Gas-Fired Engine Plant deliberately used pure ethanol as fuel for 1 3 heavy locomotives, which was then added to gasoline as an antiknock agent between 1925 and 1945. It can be said that safety and cleanliness are the main advantages of ethanol.

6. Pharmacological effects.

1. Widely used in medical disinfection (ethanol solution with a volume fraction of 75% and 5% is often used for medical disinfection).

2. Ethanol can also be used for food, such as wine. Because it acts as a good organic solvent, it is used by Chinese medicine practitioners to dissolve most of the organic components in Chinese medicine.
