• Beschreibung

  1-Pentanol is a monohydroxy alcohol. It is a colorless liquid with a characteristic odor. Its combustion properties have been studied as it shows promising features to be an alternative to gasoline and diesel fuels. The conversion of 1-pentanol to di-n-pentyl ether (DNPE) in liquid phase at 423K in a batch reactor using ion exchange resins as catalysts.

• Chemische Eigenschaften

  Amyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.
  Amyl alcohol has a characteristic fusel-like sweet and pleasant odor and burning taste. It is somewhat more toxic than ethyl alcohol.

• Chemische Eigenschaften

  1-Pentanol is a clear, colorless liquid at ambient temperatures.The air odor detection level (lowest perceptible level) was reported as 10 ppm for 1-pentanol .

• Occurrence

  Reported found in banana, sweet cherry, cranberry, bourbon, vanilla, rice bran and Brazil nut.

• Verwenden

  Raw material for pharmaceutical preparations;organic synthesis solvent.
  1-Pentanol is used as a key starting material in the production of dichloro-acetic acid pentyl ester, 2-methyltetrahydrofuran, di-n-penyl ether (DNPE), pentyl butyrate and amyl acetate. As a solvent, it is used for coating CDs and DVDs. It has been considered to be a replacement for gasoline and diesel fuels due to its combustion properties. Further, it is used as a reagent to prepare derivatives of ferulic acid and caffeic acid, which shows anticancer properties.

• Verwenden

  1-Pentanol may be used as a cosurfactant in the water-in-oil mixed surfactant microemulsions.

• Vorbereitung Methode

  1-Pentanol is made primarily by the oxo process, which involves the reaction of butenes with carbon monoxide and hydrogen in the presence of a catalyst, followed by hydrogenation. 1-Pentanol is used as a solvent, as a chemical intermediate for esters, and as a food additive and flavoring substance. The primary routes of industrial exposure are by dermal contact and inhalation.

• Definition

  ChEBI: An alkyl alcohol that is pentane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It has been isolated from Melicope ptelefolia.

• Aroma threshold values

  Detection at 1.6 to 70 ppm

• Taste threshold values

  Taste characteristics at 50 ppm: intense fusel, fermented, bready and cereal with a fruity undertone

• Lager

  Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trained onits proper handling and storage. Before entering confinedspace where amyl alcohols may be present, check to makesure that an explosive concentration does not exist. Store intightly closed containers in a cool, well-ventilated area awayfrom strong oxidizers; strong acids and hydrogen trifluoride;since violent reactions occur. Metal containers involving thetransfer of this chemical should be grounded and bonded.Where possible, automatically pump liquid from drums orother storage containers to process containers. Drums mustbe equipped with self-closing valves, pressure vacuumbungs; and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof this chemical. Sources of ignition, such as smoking andopen flames, are prohibited where this chemical is used,handled, or stored in a manner that could create a potentialfire or explosion hazard.

• läuterung methode

  Dry 1-pentanol with anhydrous K2CO3 or CaSO4, filter and fractionally distil it. It has also been treated with 1-2% of sodium and heated at reflux for 15hours to remove water and chlorides. Traces of water can be removed from the near-dry alcohol by refluxing it with a small amount of sodium in the presence of 2-3% n-amyl phthalate or succinate followed by distillation (see ethanol). Small amounts of amyl alcohol have been purified by esterifying with p-hydroxybenzoic acid, recrystallising the ester from CS2, saponifying with ethanolic-KOH, drying with CaSO4 and fractionally distilling [Olivier Recl Trav Chim Pays-Bas 55 1027 1936]. [Beilstein 1 IV 1640.]

• Inkompatibilitäten

  Forms an explosive mixture with air. Contact with strong oxidizers and hydrogen trisulfide may cause fire and explosions. Incompatible with strong acids. Violent reaction with alkaline earth metals forming hydrogen, a flammable gas.

• Waste disposal

  Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
