Solid
white or nearly white crystalline solid with a floral, orange blossom, neroli odour
2-Acetonaphthone smells similar to orange blossomand is a colorless crystalline solid (mp 56 °C). It is usually prepared by Friedel–Crafts acetylation of naphthalene (with acetyl chloride, acetic anhydride, etc.) in the presence of aluminumchloride. In polar solvents (e.g., nitrobenzene), the percentage of the simultaneously formed -isomer is lower. Methyl 2-naphthyl ketone is used in eau de cologne, soap perfumes, and detergents. It is a good fixative.

용도2-Acetonaphthone is a flavoring agent that is a crystalline solid (white or nearly white) with orange blossom-like odor. It is soluble in most fixed oils, slightly soluble in mineral oil and propylene glycol, and insoluble in glycerin. It is obtained by chemical synthesis.
일반 설명2-Acetonaphthone undergoes efficient photoreduction in the presence of tri-n-butylstannane as hydrogen donor. It is solubilized in air-saturated sodium dodecyl sulphate micelles in D2O or H2O by pulsed nitrogen laser photolysis for triplet sensitized production of singlet oxygen.
2-Acetonaphthone may be prepared by Friedel-Crafts reaction of naphthalene, acetyl chloride and AlCl3.
