Description
Acenaphthene appears as white needles. Melting point 93.6°C. Soluble in hot alcohol. Denser than water and insoluble in water. Hence sinks in water. May irritate skin and mucous membranes. Emits acrid smoke and irritating fumes when heated to decomposition. Derived from coal tar and used to make dyes, pharmaceuticals, insecticides, fungicides, and plastics.;WHITE-TO-BEIGE CRYSTALS.

Other Experimental
Enthalpy of sublimation: 78.7 kJ/mol at 299-320 K;Heat of fusion: 1.344X10+5 J/kg;Wt/vol conversion factor: 6.31 mg/cu m is equivalent to 1 ppm;Forms water-soluble, crystalline complexes with desoxycholic acid, containing two molecules of the bile acid as a rule. The complexes crystallize when concentrated solutions of the proper amount of the components in alcohol or dioxane are allowed to cool slowly.;Acenaphthene reacts with halogens preferentially at the 3-, 5-, and 6- positions. When acenaphthene is irradiated with visible light, the 1-position is accessible. Nitration and sulfonation occur at the 3-, 5-, or 6-position. Catalytic hydrogenation leads to tetra- and decahydroacenaphthene. Oxidation yields naphthalic acid or its anhydride as well as acenaphthenequinone, acenaphthenol, and acenaphthenone.;...
