salicylic acid
salicylic acid, also known as salicylic acid, salicylic acid, and o-hydroxybenzoic acid, is a fat-soluble organic acid that is widely found in nature and was originally extracted from willow bark. It is also found in the leaves of white pearl, sweet birch, cohote roots, tulip flowers, hibiscus hibiscus, maple and rabdosia leaves, mulberry fruit, the roots of Yunnan white pearl and other plants. It is also found in fruits, vegetables, nuts, herbs, jams, honey, yeast extracts, tea, coffee, juice, beer and wine. It has the chemical properties of phenl and acid. The reaction of dilute aqueous solution with feric trichloride can produce purple yellow iron complex, which decomposes in strong acid. In case of heavy metal ions such as mercuy, lead and silver, they form water-insoluble salts; It reacts with bromie water to form white precipitate of tribromophenl. Aqueous solution shows acidic reaction, can be neutralized by alkali or carbonate alkali to form sodium salt and soluble in water; When heated above the melting point, carboxylic acid is removed to form phenl

Medical field:
Antipyretic, analgesic, anti-rheumatic: salicylic acid has antipyretic, analgesic, anti-rheumatic effect, can be used to relieve fever, headache, joint pain, toothache, neuralgia and other symptoms caused by a variety of reasons.

Treatment of skin diseases:
Keratolytic: Different concentrations of salicylic acid preparations have different effects in the treatment of skin diseases. 2%-6% salicylic acid ointment can be used to treat superficial fungal skin diseases; About 10% salicylic acid cream, often used to treat acne, seborrheic dermatitis; Salicylic acid cream with a high concentration of more than 15% can be used to treat corny eyes, callus and some other wart-like lesions.
Antibacterial: Salicylic acid has an inhibitory or killing effect on some bacteria, which helps to treat skin problems caused by excessive bacterial reproduction, such as the treatment of fungal infectious skin diseases such as ringworm on the hands and feet.

In the agricultural sector:
Improve crop quality and yield: most crop plants themselves contain a certain amount of salicylic acid, and external spray of low concentration of salicylic acid solution can promote the transpiration of crops, seed germination, flowering and fruit setting, etc., thus improving the quality and yield of crops.
Prevention and control of diseases, increase crop resistance: salicylic acid can promote the activity of a variety of enzymes in crops, indirectly kill harmful bacteria and some viruses, and improve the ability of crops to resist drought, cold and salt.
Preservation effect: under the right concentration, salicylic acid can prolong the flowering period of flowers, and extend the shelf life of fruits after harvest.
Chemical industry:
Rubber industry: used as anti-scorch agent and production of ultraviolet absorbent.
Electroplating or electroless plating: as an additive in some weakly acidic electrolytes, it can also be used as a complexing agent for electroplating or electroless plating.
Synthetic flavors: can be used to prepare methyl salicylate, salicylate ethyl ester and other synthetic flavors.
Other areas:
Food industry: Trace used in food, as a preservative.
