colourless liquid

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.

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.

Uses

Dodecyl aldehyde is used as a fragrance agent. It is used as a common ingredient in perfumery. It's end applications include soap, detergent, beauty care product, household product.

Definition

ChEBI: Dodecanal is a long-chain fatty aldehyde that is dodecane in which two hydrogens attached to a terminal carbon are replaced by an oxo group. It has a role as a plant metabolite. It is a 2,3-saturated fatty aldehyde, a medium-chain fatty aldehyde and a long-chain fatty aldehyde. It derives from a hydride of a dodecane.

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.

General Description

Lauric aldehyde is one of the main aliphatic green volatile compounds in macerated grape cluster stems. It is also one of the key flavor constituents of grapefruit oil.

Flammability and Explosibility

Nonflammable

Synthesis

Dodecyl aldehyde is synthesized by catalytic dehydrogenation of Dodecanol (Lauryl alcohol).

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.]
