AURANTIOL Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
Viscous, colorless, or faintly yellow liquid; sweet lily-type odor.Soluble in alcohol (50%), fixed oils; slightly soluble in water, glycerol, and mineral oil. Combustible.
Occurrence
Has apparently not been reported to occur in nature.
Verwenden
Perfumery (fixative, muguet odor), flavoring, soap and cosmetic fragrances.
Verwenden
hydroxycitronellal is used to mask odor.
Application
This Schiff-s base Aurantiol is the most widely used of all Schiff's bases known in perfumery. Its low cost and considerable strength, its tenacity and versatility are virtues that make the product applicable in fragrances of all price levels and for numerous purposes. Obviously and almost inevitably used in Orange blossom, Neroli and related heavy florals, it finds use in smaller amounts in countless other fragrant types: Citrus blends, Ambres, and Orientals. Chyprcs, etc. It forms the steady undertone in many such sweet florals, in Honeysuckle, Frangipanni, Magnolia, exotic florals, etc. In the Citrus Cologne types, it has the ability to appear even in the initial notes, besides being a fixative. Used for nearly 50 years, it has been brought "back to life" several times, e. g., when the fruity-musky perfume was fashionable (and still is, to a certain degree), that perfume had a solid undertone of this type of material, backed up by Ethylene brassylate and Undecanolide in unusually high proportions. This base has a perceptible effect in a perfume oil at concentrations beginning well below 1%, but is often used at a much higher level.
synthetische
By hydration of citronellal (Bedoukian, 1967).
