Applications
Uses2-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.
Uses2-Acetonaphthone was used in direct time-resolved studies on singlet molecular oxygen phosphorescence in heterogeneous silica gel/cyclohexane systems.
General Description2-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.
Preparation methods
Preparation2-Acetonaphthone may be prepared by Friedel-Crafts reaction of naphthalene, acetyl chloride and AlCl3.
