Beschreibung
Carvone is a pale yellow to white clear liquid.Molecular weight=150.22; Boiling point=230℃; Flashpoint=93℃. Hazard Identification (based on NFPA 704 MRating System): Health 2, Flammability 2, Reactivity 0.
Chemische Eigenschaften
D(+)-Carvone is a clear colorless or pale yellow liquid. Darkens upon exposure to air and daylight. Sp.Gr. 0.97. BP. 230℃. Insoluble in water, soluble in alcohol and oils. Warm-herbaceous, breadlike, spicy and slightly floral odor, reminiscent of Caraway seed or Dill seed. Warm, sweet, spicy - herbaceous, breadlike taste.
Chemische Eigenschaften
Caravone occurs in different forms. l-Carvone exhibits odor of spearmint, while d-carvone exhibits odor reminiscent of caraway.
Occurrence
The optically active and inactive forms have been reported among the constituents of about 70 essential oils. The dextro form is present in carvi, Antheum graveolens, Antheum sowa, Lippia carviodora, Mentha arvensis, etc. The levo form is present in Metha vifidis var. crispa, Mentha longifolia from South Africa, Eucalyptus globules and several mint species. The racemic form is present in ginger grass, Litsea gutalemaleusis, lavender and Artemisia ferganensis. Reported found in citrus oil and juice (lemon, lime, orange), celery seed, anise, clove, coriander seed, calamus, caraway herb and dill seed.
Verwenden
(S)-(+)-Carvone can be used as a starting material to synthesize:
- (-)-Samaderine Y, a pentacyclic quassinoid.
- (-)-Ambrox, a terpenoid responsible for the odor of ambergris.
- 3β-Acetoxydrimenin (a sesquiterpene) via conjugated addition of potassium cyanide followed by base catalyzed Robinson annulation reaction.
- Thapsigargin family members such as trilobolide, nortrilobolide, and thapsivillosin F.
Verwenden
D(+)-Carvone is occasionally used in perfumes, but the lacvo-Carvone is often preferred here. It is used in flavor compositions as a fortifier for Caraway seed oil or Dill oil seed (in which oils this ketone is a major component). Since this isomer is rarely offered in the synthetic form, it has not become as popular as the laevo-Carvone. The use of Caraway-Dill flavor is confined to a few, although by volume very large, commercial products (Bread, Pickles. Spices, etc.).

Flammability and Explosibility
Not classified
Sicherheitsprofil
Poison by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
Synthese
Carvone occurs in the dextro, levo and racemic form; l-carvone can be isolated from the essential oil of spearmint or is commercially synthesized from d-limonene; d-carvone is usually prepared by fractional distillation of oil of caraway, also from dillseed and dillweed oils, but this type differs in odor and flavors.
mögliche Exposition
Carvone is found in various natural oils, including caraway and dillseed; mandarin peel and spearmint oils. A food additive, it is used in flavoring liqueurs; in perfumes and soaps.
Erste Hilfe
Skin Contact: Flood all areas of body that have contacted the substance with water. Do not wait to remove contaminated clothing; do it under the water stream. Use soap tohelp assure removal. Isolate contaminated clothing whenremoved to prevent contact by others. Eye Contact: Removeany contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 20-30 min. Seekmedical attention. Inhalation: Leave contaminated area immediately; breathe fresh air. Proper respiratory protection must besupplied to all rescuers. If coughing, difficult breathing, or anyother symptoms develop, seek medical attention at once, evenif symptoms develop many hours after exposure. Ingestion: Ifconvulsions are not present, give a glass or two of water ormilk to dilute the substance. Assure that the person’s airway isunobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting.
Lager
