  • Chemische Eigenschaften white crystalline powder
  • Chemische Eigenschaften The butylphenols include several isomers. Solid butylphenols (28805-86-9) generally have properties similar to the above:
  • Verwenden Plasticizer for cellulose acetate; intermediate for antioxidants, special starches, oil-soluble phe- nolic resins; pour-point depressors and emulsion breakers for petroleum oils and some plastics; syn- thetic lubricants; insecticides; industrial odorants; motor-oil additives.
  • Definition ChEBI: A member of the class of phenols that is phenol substituted with a tert-butyl group at position 4..
  • Allgemeine Beschreibung Crystals or practically white flakes. Has a disinfectant-like odor. May float or sink in water. Insoluble in water.
  • Air & Water Reaktionen Insoluble in water.
  • Reaktivität anzeigen Phenols, such as 4-tert-Butylphenol, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.
  • Hazard Irritant to eyes and skin.
  • Brandgefahr Combustible.
  • Kontakt-Allergie Para-tert-butylphenol is used with formaldehyde to produce the polycondensate p-tert-butylphenol-formaldehyde resins (PTBPFR). Major occupational sources are neoprene glues and adhesives in industry, in the shoemaking and leather industries or in car production. It is also used as a box preservative in box and furniture manufacture and in the production of casting molds, car brake linings, insulated electrical cables, adhesives, printing inks, and paper laminates. Para-tertbutylphenol seems to be the sensitizer
  • Sicherheitsprofil Poison by intraperitoneal route. Moderately toxic by skin contact and ingestion. A skin and severe eye irritant. Questionable carcinogen with experimental neoplastigenic data. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid and irritating fumes. See also PHENOL and other butyl phenols.
  • mögliche Exposition Butylphenols may be used as intermediates in manufacturing varnish and lacquer resins; as a germicidal agent in detergent disinfectants; as a pour point depressant, in motor-oil additives; de-emulsifier for oil; soap-antioxidant, plasticizer, fumigant, and insecticide
  • 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. 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. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit
  • Versand/Shipping UN2430 Alkylphenols, solid, n.o.s. (including C2-C12 homologues), Hazard class: 8; Labels: 8— Corrosive material
  • läuterung methode Crystallise the phenol to constant melting point from pet ether (b 60-80o). It sublimes in vacuo. Also purify it via the benzoate, as for phenol. The salicylate ester [87-18-30] has m 63-64o (from aqueous EtOH, or EtOH). [Beilstein 6 IV 3296.]
  • Inkompatibilitäten Vapors may form explosive mixture with air. These phenol/cresol materials can react with oxidizers; reaction may be violent. Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may cause the gas to ignite and explode. Heat is also generated by the acid-base reaction with bases; such heating may initiate polymerization of the organic compound. React with boranes, alkalies, aliphatic amines, amides, nitric acid, sulfuric acid. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). These reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid and can explode when heated. Many phenols form metal salts that may be detonated by mild shock
