Phenol (chemical formula: C6H5OH, PhOH), also known as carbolic acid, hydroxybenzene, is the simplest phenolic organic substance, a colorless crystal at room temperature. Poisonous. Phenol is a common chemical and is an important ingredient in the production of certain resins, fungicides, preservatives, and medicines such as aspirin.

Is an important raw material for organic synthesis, used in the production of phenolic resin, bisphenol A, phenolphthalide, picric acid, salicylic acid, alkyl phenol and other chemicals, also can be used as A solvent. Widely used in the manufacture of phenolic resin, epoxy resin, polyamide fiber, plasticizer, developer, preservative, insecticide, fungicide, dye, medicine, perfume and explosives, etc. Used in the oil field industry, also is the important organic chemical raw materials, use it to preparing phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, phenolphthalein, Luo acetyl ethoxy, aniline and other chemical products and intermediates in the chemical raw materials, alkylphenol, synthetic fibre, plastic, synthetic rubber, medicine, pesticide, spices, dye, paint and has A wide range of applications such as oil refining industry. Used as analytical reagents, for example, as solvents and organic modifiers for liquid chromatography, for the determination of ammonia by photometric methods, and for the determination of carbohydrates by thin-layer methods. Also used as a preservative, disinfectant, and used in organic synthesis. Widely used in plastics, dyes, medicine, synthetic rubber, spices, coatings, oil refining, synthetic fiber and other industries. As an antioxidant in fluoroborate tin plating and tin alloy, and as other electroplating additives. Used in the production of phenolic resin, bisphenol A, caprolactam, aniline, alkyl phenol, etc. Used as a selective solvent for refined lubricating oils in the petroleum refining industry, as well as in the plastics and pharmaceutical industries.
