PENTYL ETHER Usage And Synthesis
  • Chemical PropertiesCommercial diamyl ether consists principally of di-n-amyl ether and di-isoamyl ether, with small percentages of isomeric amyl ethers and diamylene. It is a colorless to light yellow liquid which is quite stable. It is insoluble in water but soluble in methanol, ethyl ether, ethyl acetate, acetone, aliphatic and aromatic hydrocarbons, fixed oils, oleic and hot stearic acids, hot paraffin and carnauba waxes, the latter two solidifying when cooled. Unlike the lower aliphatic ethers, it will not dissolve nitrocellulose when admixed with ethanol. However, a mixture of diamyl ether and 20% ethanol will dissolve ethylcellulose.
  • UsesIndustrial solvent.
  • HazardNarcotic in high concentration.
  • Industrial usesThe commercial diamyl ether consists of a blend of di-AZ-amyl and di-iso-amyl ether, a small amount of isomeric amyl ethers and diamylene. A blend of diamyl ether and 20% ethanol will dissolve ethyl cellulose.
  • Safety ProfilePoison by intravenous route. Flammable liquid when exposed to heat or flame; reacts with oxidizing materials. To fight fire, use alcohol foam, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHERS
  • Purification MethodsRepeatedly reflux amyl ether over sodium and distil it. [Beilstein 1 IV 1643.]
