Chemische Eigenschaften
Clear colorless liquid
Chemische Eigenschaften
10-Undecenal has a characteristic fatty, rose odor on dilution. It has an unpleasant sweet, fatty taste. This compound tends to polymerize.
Chemische Eigenschaften
10-Undecenal was identified, for example, in coriander leaf extract. It is a colorless liquid with a fatty, green, slightly metallic, heavy, floral odor. The aldehyde can be synthesized from undecylenic acid, for example, by hydrogenation of the acid chloride (Rosenmund reduction) or by reaction with formic acid in the vapor phase in the presence of titanium dioxide. In perfumery, 10-undecenal is one of the aldehydes essential for creating the “aldehydic note.”
Mixtures containing undecenals with the double bond in other positions (9-, 8-, 7-) are also marketed and used in fragrances, for example, Aldehyde C₁₁ Iso (Givaudan), Intreleven aldehyde (IFF).
Occurrence
Reported found in coriander leaf (Coriandrum sativum L.).
Verwenden
10-Undecylenic Aldehyde is derived from the reduction of Undecylenic Acid (U788820) which is used for the manufacture of pharmaceuticals, cosmetics and perfumery, including antidandruff shampoos, antimicrobial powders and as a musk in perfumes and aromas.
synthetische
By oxidation of the corresponding alcohol or reduction of the corresponding acid; by passing vapors of formic acid and undecylenic acid over TiO2 at 250°C under pressure; by passing vapors of undecylenic acid and methanol over a manganese dioxidebased catalyst; or by reduction of ethyl undecylenate with lithium hydride and sodium in tetrahydrofuran solution at very low temperature (–50°C).
Definition
ChEBI: 10-undecenal is an undecenal.
Taste threshold values
Taste characteristics at 2.5 ppm: fatty, oily and aldehydic with a mandarin, citrus nuance.
