glycerol. Combustible.
Chemical Properties
Geranyl acetate has a pleasant, fowery odor reminiscent of rose lavender It has a burning taste, initially somewhat bitter and then sweet.
Chemical Properties
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
Definition
ChEBI: A monoterpenoid that is the acetate ester derivative of geraniol.
Preparation
From geraniol by acetylation or by fractional distillation of essential oils in which it is present.
Aroma threshold values
Detection: 9 to 460 ppb.
Taste threshold values
Taste characteristics at 20 ppm: green, foral, fruity with a citrus nuance.
Flammability and Explosibility
Nonflammable
Purification Methods
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.]
