Ethanol is mainly used in the field of solvents, sterilization, etc. The specific applications are as follows

1, the solvent field: solvent; organic synthesis; crystallization of various compounds; detergent; extractant.

Edible alcohol can be blended white wine; used as an adhesive; nitro spray paint; varnish, cosmetics, ink, paint stripper and other solvents, as well as pesticides, pharmaceuticals, rubber, plastics, synthetic fibers, detergents and other raw materials for the manufacture of raw materials, but also to do antifreeze, fuels, disinfectants and so on.

2、Sanitizing field: volume fraction of 99.5% or more of the alcohol is called anhydrous alcohol.

3, the use of biology: chloroplast pigment can be soluble in organic solvent anhydrous ethanol (or acetone), so anhydrous ethanol can be extracted chloroplast pigment.

95% alcohol is used for wiping UV lamps. This type of alcohol is commonly used in hospitals, whereas in the home only 70% to 75% alcohol will be used for sterilization. This is because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria and making it difficult to kill the bacteria completely. If the concentration of alcohol is too low, although it can enter the bacteria, but can not coagulate the proteins in its body, also can not kill the bacteria completely. Among them, 75% of the alcohol disinfection effect is the best.

40%~50% alcohol can prevent bedsores. Long-term bedridden patients of the back, waist, buttocks due to long-term pressure can cause bedsores, such as massage will be a small amount of 40% ~ 50% alcohol poured into the hands, evenly massaging the patient's pressure parts, can achieve the promotion of local blood circulation, to prevent the formation of decubitus ulcers purpose.

25%~50% alcohol can be used for physical antipyretic. Patients with high fever can use it to rub their bodies to achieve the purpose of lowering the temperature.
