Phenol, also known as carbonic acid, hydroxy benzene, is the German chemist Runge F (Runge F) in 1834 in the coal tar found, is the most simple phenolic organic matter, a weak acid. At room temperature for a colorless crystal, toxic. Phenol is a common chemical, is the production of certain resins, fungicides, preservatives and drugs (such as aspirin) an important raw material. Phenol is corrosive, at room temperature, slightly soluble in water, soluble in organic solvents; when the temperature is higher than 65 ℃, with the water in any proportion of miscible. The solution gets on the skin and can be washed with alcohol, and the phenol is exposed to pink in the air.
Phenol - the main purpose
Important organic synthesis materials for the use of phenolic resin, bisphenol A, phenolphthalein, picric acid, salicylic acid, alkyl phenol and other chemicals can also be used as a solvent. Widely used in the manufacture of phenolic resins, epoxy resins, nylon fibers, plasticizers, developers, preservatives, pesticides, fungicides, dyes, pharmaceuticals, spices and explosives.
Phenol is toxic. Phenol and its concentrated solution on the skin has a strong stimulating effect, if inadvertently dip the phenol on the skin, the application of alcohol or polyethylene glycol cleaning; if the larger or mixed with chloroform, you need to first aid. Dirty clothes also need to use plenty of water to rinse. Pathological changes caused by pathogenic phenol and its compounds are largely dependent on their concentration. Low concentrations of phenol absorbed by the body, the liver tissue detoxification function will make it lose most of the toxicity, and with the urine. But may cause chronic poisoning, such as the emergence of varying degrees of dizziness, headache and other neurological symptoms, as well as loss of appetite, dysphagia, vomiting and diarrhea and other gastrointestinal symptoms. This chronic poisoning, after treatment, generally do not leave sequelae. Drinking chlorine in drinking water will produce disgusting odor, can also cause gastrointestinal symptoms, such as nausea, vomiting, diarrhea and so on.
Store in a cool, ventilated warehouse. Away from fire, heat. Avoid light. The reservoir temperature does not exceed 30 ℃, relative humidity does not exceed 70%. Packaging sealed. Should be with the oxidants, acids, alkaloids, edible chemicals stored separately, avoid mixed storage. Storage area should be equipped with the corresponding variety and quantity of fire equipment, and should be equipped with appropriate materials to contain spills. We should strictly implement the "five pairs" management system of extremely toxic items.
