| Hazard Information | Back Directory | [General Description]
Light yellow crystalline solid. Insoluble in water. | [Reactivity Profile]
A nitrated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data is not available for this compound, however, MUSK KETONE is probably combustible. | [Chemical Properties]
It forms yellowish crystals with a sweet, very
persistent, slightly animal musk odor.Musk ketone is prepared by Friedel–Crafts
acetylation of 1,3-dimethyl-5-tert-butylbenzene and nitration of the resulting 2,6-
dimethyl-4-tert-butylacetophenone with nitric acid.
Musk ketone is widely used as a fixative in blossom and fantasy compositions. | [Chemical Properties]
White to light yellow crystal powde | [Occurrence]
Has apparently not been reported to occur in nature. | [Uses]
Musk ketone is used as fragrance and fixative in after-shave lotions, perfumes, ete. | [Definition]
ChEBI: 4'-tert-Butyl-2',6'-dimethyl-3',5'-dinitroacetophenone is an aromatic ketone. | [Preparation]
Nitration of the corresponding benzene derivative (Bedoukian, 1967). | [Flammability and Explosibility]
Notclassified(100%) | [Purification Methods]
Purify the ketone by recrystallisation from MeOH. It has a strong odour of musk and is used in perfumery. [Fuson et al. J Org Chem 12 587 1947, Beilstein 7 IV 808.] |
