Phenol CAS108-95-2

Phenol, commonly known as carbolic acid, is defined as C6H6O molecular formula. It is mainly prepared by the oxidation and decomposition of isopropyl benzene. It is an important organic chemical raw material and can be used in the production of phenolic resin, bisphenol A and other chemical products and intermediates, as well as as a solvent and disinfectant.

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.

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.

Leakage emergency treatment

Isolate the contaminated area of leakage and restrict access. Cut off the fire. It is recommended that emergency personnel wear dust masks (full face masks) and protective clothing.

Small leakage: Cover with dry lime and soda ash.

Large leakage: Collect and recycle or transport to a waste disposal site for disposal.

Operation handling store

Operation precautions: closed operation, provide sufficient local exhaust air. Quarantine operations where possible. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, gas penetrating protective clothing, and chemical-resistant gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid producing dust. Avoid contact with oxidants, acids and alkalis. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have harmful residues.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. Avoid light. The temperature of the reservoir shall not exceed 30℃, and the relative humidity shall not exceed 70%. The package is sealed. It should be stored separately from oxidizers, acids, alkalis and edible chemicals, and should not be mixed. Equipped with the corresponding variety and quantity of fire equipment. Storage areas should be equipped with suitable materials to contain leaks. The "five-double" management system for extremely toxic substances should be strictly implemented.
