Beschreibung
Geranyl acetate has a pleasant, flowery odor reminiscent of rose
lavender. It has a burning taste, initially somewhat bitter and then
sweet. It is produced from geraniol by acetylation or by fractional
distillation of essential oils in which it is present.
Chemische Eigenschaften
Geranyl Acetate occurs in varying
amounts in many essential oils: up to 60% in oils from Callitris and Eucalyptus
species and up to 14% in palmarosa oil. A smaller amount occurs in, for example,
geranium, citronella, petitgrain, and lavender oils. Geranyl acetate is a liquid with
a fruity rose note, reminiscent of pear and slightly of lavender. It is used frequently
in perfumery not only to create floral, fruity nuances (e.g., rose) but also for citrus
and lavender notes. A small amount is added to fruit aromas for shading.
Occurrence
Reported found in a large number of essential oils; Ceylon citronella, palmarose, lemongrass, petitgrain, neroi bigarade, geranium, coriander, lavender, carrot, sassafras, in various Callitris species (C verrucosa, C robusta, and others) and Eucalyptus species (E acervula, E urnigera, etc ) A 60% level has been reported in the essential oil of Eucalyptus macar- thuri and up to 50% in the essential oil of Orthodon citraliferum; also identifed in bitter orange essential oil and Cymbopogon citratus oil Also reported found in citrus peel oils and juices, black currants, pineapple, celery seed, cinnamon, ginger, pepper- mint oil, corn mint oil, nutmeg, mace, thymus, hop oil, beer, rum, grape wines, coffee, tea, passion fruit, tomato, almond, muscal grape, cardamom, coriander leaf and seed, tarragon, lovage, Ocimum basilicum, laurel, myrtle leaf and berry, rosemary, clary sage and calabash nutmeg
Verwenden
β-Geranyl Acetate is found in essential oils such as Moroccan commercial essential oils which has anti-oxidant, anti-inflammatory and anti-proliferative activities; and in Salvia scabiosifolia from Bulgaria.
synthetische
From geraniol by acetylation or by fractional distillation of essential oils in which it is present.
Definition
ChEBI: A monoterpenoid that is the acetate ester derivative of geraniol.
Allgemeine Beschreibung
Clear colorless liquid with an odor of lavender.
Air & Water Reaktionen
Insoluble in water.
Reaktivit?t anzeigen
Geranyl acetate should be protected from light. Geranyl acetate reacts with strong oxidizing agents.
Brandgefahr
Geranyl acetate is probably combustible.
Sicherheitsprofil
Mildly toxic by
ingestion. A human skin irritant. Mutation
data reported. Combustible liquid. When
heated to decomposition it emits acrid
smoke and irritating fumes. See also
ESTERS.
l?uterung methode
Purify the fragrant smelling geranyl acetate by fractional distillation at as high a vacuum as possible. It is very soluble in EtOH but insoluble in H2O. [Beilstein 2 H 140, 2 I 65, 2 II 153, 2 III 299, 2 IV 204.]
