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.
colourless or pale yellow liquid
Caravone occurs in different forms. l-Carvone exhibits odor of spearmint, while d-carvone exhibits odor reminiscent
of caraway.
Carvone is a pale yellow to white clear liquid.
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.
(
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.
ChEBI: A carvone having (S) configuration.
Detection: d-Carvone: 6.7 to 820 ppb; l-carvone: 2.7 to 600 ppb
Pale yellow or colorless liquid.
May be sensitive to prolonged exposure to light and air. Insoluble in water.
D(+)-Carvone may be sensitive to prolonged exposure to light and air. Incompatible with strong oxidizing agents and strong reducing agents
D(+)-Carvone is combustible.
Flammability and Explosibility
Not classified
Poison by ingestion and
skin contact. A skin irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes.
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.
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.
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.
