Allgemeine Beschreibung
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.
Sicherheitsprofil
Dodecyl aldehyde is 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.
Synthese
Dodecyl aldehyde is synthesized by catalytic dehydrogenation of Dodecanol (Lauryl alcohol).
Stoffwechsel
See monograph on aldehyde C-8*
läuterung methode
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.]
