Benzyl ether Usage And Synthesis
  • Chemical PropertiesDibenzyl ether is a clear, almost colorless liquid. It is miscible with alcohols and ethers, but insoluble in water. Dibenzyl ether is used as special solvent and delustering agent for textiles.
  • Chemical PropertiesDibenzyl ether has a slightly earthy, mushroom-like odor with a rosy undertone.
  • UsesPlasticizer for nitrocellulose; solvent in perfumery.
  • DefinitionChEBI: A benzyl ether in which the oxygen atom is connected to two benzyl groups.
  • PreparationAs a by-product in the preparation of benzyl alcohol by hydrolysis of benzyl chloride; by using a concentrated caustic instead of carbonate, yields can be improved to 50% or higher.
  • General DescriptionColorless liquid with a mild odor.
  • Air & Water ReactionsOxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water.
  • Reactivity ProfileBenzyl ether can act as a base to form salts with strong acids and addition complexes with Lewis acids. May react violently with strong oxidizing agents. Burns readily but relatively inert in other reactions, which typically involve the breaking of the carbon-oxygen bond.
  • HazardModerately toxic by ingestion. A skin irri- tant.
  • Health HazardInhalation may cause nausea because of disagreeable odor. Contact of liquid with eyes causes mild irritation. Prolonged exposure of skin to liquid causes reddening and irritation. Ingestion produces nausea.
  • Fire HazardBenzyl ether is combustible.
  • Purification MethodsReflux the ether over sodium, then distil it under reduced pressure. It been purified by fractional freezing. [Beilstein 6 IV 2240.]
