Dodecyl aldehyde Chemical Properties,Usage,Production

  • Chemical Properties Dodecanal is a colorless liquid with a waxy odor; in high dilution, it is reminiscent of violets. Dodecanal occurs in several citrus oils and has been found in small amounts in essential oils obtained from several Pinus species. It is used in perfumery in conifer fragrances with fatty, waxy notes, but also in many other odor types. It is added to aroma compositions to obtain citrus notes.
  • Chemical Properties Lauric aldehyde has a characteristic fatty odor reminiscent of violet on dilution and a fatty, woody taste.
  • Chemical Properties colourless liquid
  • Occurrence Reported found in the essential oils of lemon, sweet orange, bitter orange, mandarin, Mexican lime and petitgrain bigarade and in the turpentine of some varieties of pine. Also reported found in berries, apple, carrot, celery, cucumber, rutabaga, ginger, wheat bread, cheeses, milk, butter, caviar, fatty fish, roast chicken, cooked beef and pork, hop oil, beer, rum, peanut, mango, kelp, coriander seed and leaf, lovage leaf, buckwheat, cherimoya, mountain papaya, clam, scallop, loganberry and mate.
  • Uses Dodecanal is a fragrance agent that is found in soaps, perfumes as well as in food flavoring materials.
  • Preparation By oxidation of the corresponding alcohol or reduction of the acid
  • Aroma threshold values Detection: 0.5 to 1.5 ppb; aroma characteristics at 2.0%: soapy, waxy, aldehydic, citrus, orange rindy with floral nuances
  • Taste threshold values Taste characteristics at 2.0 ppm: soapy, waxy, citrus, orange mandarin.

  • Safety Profile Mildly toxic by ingestion. A human and experimental skin irritant. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
  • Metabolism See monograph on aldehyde C-8*
  • Purification Methods Convert lauraldehyde to the bisufite addition compound by shaking with saturated aqueous NaHSO3 for 1hour. The precipitate is filtered off, washed with ice cold water, EtOH and ether, then decomposed with aqueous Na2CO3. The aldehyde is extracted into diethyl ether which, after drying and evaporating, gives an oil which is fractionally distilled under vacuum. [Beilstein 1 IV 3380.]
