Phenol is used in the manufacture or production of explosives, fertilizer, coke, illuminating gas, lampblack, paints, paint removers, rubber, perfumes, asbestos goods, wood preservatives, synthetic resins, textiles, drugs, and pharmaceutical preparations. It is also used extensively as a disinfectant in the petroleum, leather, paper, soap, toy, tanning, dye, and agricultural industries. Phenol is a systemic poison and constitutes a serious health hazard. The risks of using it in the laboratory must be fully assessed before work begins. Typical MEL 2 ppm; typical OEL 1 ppm.
  • Chemische Eigenschaften Phenol is a colorless to light-pink, crystalline solid. Sweet, acrid odor. Phenol liquefies by mixing with about 8% water. The Odor Threshold in air is 0.04 ppm and in water is 7.9 ppm.
  • Chemische Eigenschaften Phenol, C6H5OH, also known as carbolic acid and phenylic acid, is a white poisonous crystalline solid that melts at 43 °C (110 OF) and boils at 182°C (360 OF). Phenol has a sharp burning taste,a distinctive odor, and it irritates tissue. It is toxic not only by ingestion or inhalation, but also by skin absorption. Phenol is soluble in water,alcohol,and ether. It is used in the production of resins,germicides,weedkillers,pharmaceuticals, and as a solvent in the refining of lubricating oils.
  • Verwenden Purified for molecular genetics applications
  • Verwenden phenol is frequently used for medical chemical face peels. It may trap free radicals and can act as a preservative. Phenol, however, is an extremely caustic chemical with a toxicity potential. It is considered undesirable for use in cosmetics. even at low concentrations, it frequently causes skin irritation, swelling, and rashes.
  • Definition ChEBI: An organic hydroxy compound that consists of benzene bearing a single hydroxy substituent. The parent of the class of phenols.
  • Allgemeine Beschreibung A solid melting at 110°F. Colorless if pure, otherwise pink or red. Flash point 175°F. Density 9.9 lb / gal. Vapors are heavier than air Corrosive to the skin (turning skin white) but because of its anesthetic quality numbs rather than burn. Lethal amounts can be absorbed through the skin. Used to make plastics and adhesives.

  • Reaktivität anzeigen PHENOL is a weak acid. Reacts exothermically with bases. Reacts with strong oxidizing agents. Emits acrid smoke and irritating fumes when heated to decomposition. Undergoes, in the presence of aluminum chloride, potentially explosive reactions with nitromethane, butadiene, formaldehyde, peroxodisulfuric acid, peroxosulfuric acid, and sodium nitrite . Reacts violently with sodium nitrate in the presence of trifluoroacetic acid [Bretherick, 5th ed., 1995, p. 770]. May corrode lead, aluminum and its alloys, certain plastics, and rubber. Phenol may explode in contact with peroxodisulfuric acid (Dns, J. Ber., 1910, 43, 1880; Z. Anorg. Chem., 1911, 73, 1911.) or peroxomonosulfuric acid. (Sidgwick, 1950, 939)
  • AUFNAHMEWEGE Schnelle Aufnahme in den Körper durch Inhalation der Dämpfe, über die Haut und durch Verschlucken.
  • INHALATIONSGEFAHREN Beim Verdampfen bei 20 °C tritt langsam eine gesundheitsschädliche Kontamination der Luft ein.
  • Health Hazard Toxic hazard rating is very toxic: probable oral lethal dose (human) is 50-500 mg/kg. Ingestion of 1 gram has been lethal to humans. Lethal amounts may be absorbed through skin or inhaled. Industrial contact can cause chronic poisoning with kidney and liver damage. Persons affected with hepatic or kidney diseases are at a greater risk.
  • Health Hazard Exposures to phenol cause adverse health effects and poisoning. Phenol is absorbed very rapidly through surfaces of the skin, lungs, and stomach. The symptoms of prolonged exposures and poisoning include, but are not limited to, vomiting, diffi culty in swallowing, diarrhea, lack of appetite, headache, fainting, dizziness, mental disturbances, and skin rash. Direct contact with phenol causes burning of the mouth, irritation to the eyes, nose, and dermatitis, discoloration of the skin, and damage to the liver and kidneys. Exposure to phenol in different concentrations is known to cause mental disturbances, depression of the CNS, and coma.
  • Health Hazard Phenol is a corrosive and moderately toxic substance that affects the central nervous system and can cause damage to the liver and kidneys. Phenol is irritating to the skin but has a local anesthetic effect, so that no pain may be felt on initial contact. A whitening of the area of contact generally occurs, and later severe burns may develop. Phenol is rapidly absorbed through the skin, and toxic or even fatal amounts can be absorbed through relatively small areas. Exposure to phenol vapor can cause severe irritation of the eyes, nose, throat, and respiratory tract. Acute overexposure by any route may lead to nausea, vomiting, muscle weakness, and coma. Contact of phenol with the eyes may cause severe damage and possibly blindness. Ingestion of phenol leads to burning of the mouth and throat and rapid development of digestive disturbances and the systemic effects described above. As little as 1 g can be fatal to humans. Phenol is regarded as a substance with good warning properties.
    Chronic exposure to phenol may cause vomiting, diarrhea, dizziness, difficulty in swallowing, headache, skin discoloration, and injury to the liver. Phenol has not been shown to be a carcinogen in humans. There is some evidence from animal studies that phenol may be a reproductive toxin.

  • Erste Hilfe If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. If concentrated phenol gets on a large area of the skin, immediately rush victim to shower and use at full blast; remove all contaminated clothing; scrub the contaminated area with soap for at least 10 minutes—water alone may be harmful. If polyethyleneglycol-300 is available, swab exposed area with cotton soaked in it. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Rinse mouth. Give plenty of water and/or vegetable oil to drink. Do not allow the consumption of alcohol. Induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 2448 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
  • Lager Because of its corrosivity and ability to penetrate the skin, all work with phenol and its solutions should be conducted while wearing impermeable gloves, appropriate protective clothing, and splash goggles. Operations with the potential to produce dusts or aerosols of phenol or its solutions should be carried out in a fume hood.

  • läuterung methode Steam is passed through a boiling solution containing 1mole of phenol and 1.5-2.0moles of NaOH in 5L of H2O until all non-acidic material has distilled. The residue is cooled, acidified with 20% (v/v) H2SO4, and the phenol is separated, dried with CaSO4 and fractionally distilled under reduced pressure. It is then fractionally crystallised several times from its melt [Andon et al. J Chem Soc 5246 1960]. Purification via the benzoate has been used by Berliner, Berliner and Nelidow [J Am Chem Soc 76 507 1954]. The benzoate,(m 70o, b 314o/760mm), is crystallised from 95% EtOH, then hydrolysed to the free phenol by refluxing with two equivalents of KOH in aqueous EtOH until the solution becomes homogeneous. It is acidified with HCl and extracted with diethyl ether. The ether layer is freed from benzoic acid by thorough extraction with aqueous NaHCO3, and, after drying and removing the ether, the phenol is distilled. Phenol has also been crystallised from a 75% w/w solution in water by cooling to 11o and seeding with a crystal of the hydrate. The crystals are centrifuged off, rinsed with cold water (0-2o), saturated with phenol, and dried. It can be crystallised from pet ether [Berasconi & Paschalis J Am Chem Soc 108 2969 1986]. Draper and Pollard [Science 109 448 1949] added 12% water, 0.1% aluminium (can also use zinc) and 0.05% NaHCO3 to phenol, and distilled it at atmospheric pressure until the azeotrope was removed, The phenol was then distilled at 25mm. Phenol has also been dried by distillation from the *benzene solution to remove the water/*benzene azeotrope and the excess *benzene, followed by distillation of the phenol at reduced pressure under nitrogen. Processes such as this are probably adequate for analytical grade phenol which has as its main impurity water. Phenol has also been crystallised from pet ether/*benzene or pet ether (b 40-60o). The purified material is stored in a vacuum desiccator over P2O5 or CaSO4. [Beilstein 6 IV 531.]
  • Inkompatibilitäten Vapors may form explosive mixture with air. The aqueous solution is a weak acid. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, calcium hypochlorite; aluminum chloride. acids. Reacts with metals.
  • Flammability and Explosibility Phenol is a combustible solid (NFPA rating = 2). When heated, phenol produces flammable vapors that are explosive at concentrations of 3 to 10% in air. Carbon dioxide or dry chemical extinguishers should be used to fight phenol fires.
