Phe nol is one of the main components of coal tar, and Runge discovered phe nol from coal tar in 1834, and Laurent first made crystalline phe ol in 1841. Phen ol is the product of a hydrogen atom on the benzene ring being replaced by a hydroxyl group. Ph enols exist in nature either in their free form or in the form of derivatives (more often in the form of derivatives). The pure product is white or colorless and easy to deliquescence. In the air or in case of unclean substances, it gradually turns into reddish crystals. It has a special odor, is toxic and highly corrosive. The relative molecular mass is 94.11. The relative density is 1.0576. Melting point 43 °c. Boiling point 181.7 °C, 120.7 °C (13.3×104Pa), 90.2 °C (3.33×103Pa), 70.9 °C (1.33×103Pa), 33.6 °C (1.33×102Pa). The freezing point is 40.85 °c. Flash point 85 °c. The refractive index is 1.5418 (41 °C). Vapor pressure 70.7Pa (25°C). Soluble in water, miscible with ethanol, ether, acetic acid, chlor oform, benzene and carbon disulfide. Chemicalbook and water form an azeotropic mixture, at this time the content of this product is 9.2%, the azeotropic point is 99.6 °C. The reactivity of p henol is mainly the reaction of hydroxyl groups and aromatic rings. The hydrogen of the hydroxyl group is easily dissociated into hydrogen ions, so it is acidic, and reacts with sod ium hydroxide to generate sodium phe nol; However, the acidity of p henol is lower than that of carboxylic acid and carbonic acid, so sodium ph enol is free ph enol in carbonated aqueous solution; Ph enol is easily oxidized to form benzo quinone (pink), which is further oxidized to form brown polymers; React with metal zinc, can be reduced to benzene; Under the action of nickel catalyst, hydrogenation can be reduced to cyclohexanol; Hydroxyl groups can also form ethers or esters; The reaction on the ph enol aromatic ring is mainly manifested as electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, alkylation, acylation, carboxylation and coupling reactions with diazo salts, these electrophilic reactions mainly occur in the o-and para-positions of hydroxyl groups; The aromatic ring has a high reaction ability to the carbonyl groups of ketones and aldehydes, such as reacting with ac etone to generate bisp henol A; Under the catalytic action of acid and alkali, phe nol and formaldehyde can form phen olic polymers. Phe nol is a food spice temporarily allowed in China's GB2760-1996 regulations.

Ph enol is an important organic chemical raw material, with which phen olic resin, caprolactam, bisph enol A, salicylic acid, picric acid, pentachlorophen ol, 2,4-D, adipic acid, phe nolphthalein N-acetyethoxyaniline and other chemical products and intermediates, in chemical raw materials, alkyl ph enols, synthetic fibers, plastics, synthetic Chemicalbook rubber, pharmaceuticals, pesticides, fragrances, dyes, coatings and oil refining and other industries have important uses. In addition, pheno l can also be used as a solvent, experimental reagent and disinfectant. From 1997 to 2002, the demand for pheno l in major regions such as the United States, Western Europe and Japan maintained an average annual growth rate of 4.2%.
Phen ol is an important raw material for pesticide production, which can produce insecticide carbuan, instant thion, vegetable and fruit phosphorus, fungicide prochloramide, triazolone, difenoconazole, herbicide 2,4-drops, 2,4-drop butyl ester and rodenticide poison rat phosphorus, brominated Chemicalbook poison rat phosphorus. In addition, pheno l alkylation to generate alkyl phe nols, such as nonylphe nol, dinonylphe nol, secoctylphen ol, and polyaryl ph enols, such as 2-methylbenzylphen ol, 2,2-dimethylbenzylp henol, etc., are important intermediates of surfactants.
