Phenol (phenol or phenyl hydroxide, commonly known as carbolic acid) is defined as: The molecular formula is C6H6O, which is mainly prepared by the oxidation and decomposition of isopropyl benzene. It is an important organic chemical raw material, which can be used for the production of phenolic resin, bisphenol A and other chemical products and intermediates, and also used as solvents and disinfectants.
Phenol is an organic compound with the chemical formula C6H5OH. It is a colorless needle-like crystal with a distinctive odor and is toxic. It is an important raw material in the production of certain resins, fungicides, preservatives, and medicines (such as aspirin). It can also be used for disinfection of surgical instruments and excrement treatment, skin sterilization, itching and otitis media. Melting point 43℃, slightly soluble in water at room temperature, easily soluble in organic solvents; When the temperature is higher than 65 ° C, it can be miscible with water in any proportion. Phenol is corrosive and denatures local proteins upon contact. Its solution can be washed with alcohol when it touches the skin. Small amounts of phenol exposed to air are oxidized to quinone by oxygen and appear pink. This method is usually used to test phenol when ferric ions turn purple.
On October 27, 2017, the preliminary list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was collated for reference, and phenol was in the list of 3 types of carcinogens.

industry
Phenol is an important organic chemical raw material, which can be used to produce phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, 2,4-D, adipic acid, phenolphthalein n-acetylethoxyaniline and other chemical products and intermediates. It has important uses in chemical raw materials, alkyl phenols, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings and oil refining industries. In addition, phenol can also be used as a solvent, experimental reagent and disinfectant, and the aqueous solution of phenol can separate the protein from DNA on the chromosome in plant cells, which is convenient for DNA staining.
Medical treatment
1. Equipment disinfection and excrement treatment of 1% ~ 5% aqueous solution.
2, skin sterilization and anti-itch: 2% ointment applied to the affected area.
3, otitis media with 1% ~ 2% phenol glycerol ear drops, 3 times a day. Preparations and specifications Phenol ointment: 2%. Phenol glycerol: ①1%; ②2%. Administration indicates that this product has strong tissue penetration and is only used on a small area of skin. High concentration of external use can cause tissue damage and even necrosis. Aqueous solution is used on the body surface, the concentration should not exceed 2%, and it is not packaged after external use. Adverse reactions This product is corrosive and irritating to tissues. It has been reported that the use of phenol to clean cradles and mattresses in poorly ventilated places has caused neonatal hyperbilirubinemia, which has proved fatal to infants. Contraindications for children with diaper dermatitis and infants under 6 months old. Avoid application on broken skin and wounds.
