Chemische Eigenschaften
6,10-Dimethyl-5,9-undecadien-2-one has a green and rosy floral odor and fresh-floral, light, but rather penetrating sweet-rosy, slightly green, magnolia-like odor. It blends well in lavender and fruity notes, where it imparts a clean and natural character. It helps to round out floral bouquets
Occurrence
Reported found in oil of citronella, yellow passion fruit, peppermint, Scotch spearmint oil, Japanese seafood, scallop, tomato, tomato paste, citrus peel oils, carrots, papaya, melon, Parmesan cheese, milk powder, cognac, tea, starfruit, figs, mango, red sage, nectarines, clams, pork, anise, and hyssop
Verwenden
(E)-6,10-Dimethylundeca-5,9-dien-2-one is diastereoselective used in preparation of Geranyl Acetone by Carroll reaction of linalool with Acetoacetate. This ketone, which was developed as an intermediate in the synthesis of Nerolidol, has been suggested for use in perfume compositions, particularly in soap perfumes, where its superior stability makes it a very reliable Itorahzer anct sweetener in floral compositions.
synthetische
By reaction of linalool and ethyl acetoacetate with an alkaline catalyst and subsequent rearrangement and decarboxylation.
Definition
ChEBI: A monoterpene ketone in which an (E)-geranyl group is bonded to one of the alpha-methyls of acetone. It is a component of essential oils from various plants including Nelumbo nucifera.
Aroma threshold values
Detection: 60 ppb to 6.4 ppm
Taste threshold values
Taste characteristics at 12 ppm: floral, fruity, fatty, green, pear, apple and banana nuances
