Uses
Uses in perfumery :
Musk Ketone is used in women perfumes for a powdery effect. Goes on well with white flowers accords.
Solubilization issues in alcohol.
Mostly used in fine fragrance, less and less beacause of its vintage connotation.
Year of discovery :
Patented in 1893 by Willem Mallmann and transferred to the Laire factories in 1896. The reason? W. Mallmann illegally produced this compound chemically very close to musk Xylene, itself patented by the Fabriques DeLaire in 1888.
Natural availability :
Musk Ketone is not available in its natural state.
Isomerism :
Musk Ketone is a nitrated musk with no isomer used in perfumery.
Synthesis precursor :
Musk Ketone is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Musk Ketone is synthesized from 1,3-dimethyl-5-tert-butylbenzene, by a Friedel-Craft acetylation, with chloroacetic acid and in the presence of aluminum chloride. This reaction is followed by a nitration of the obtained compound with nitric acid.
