Preparation of 3-acetylphenanthrene
132 g of anhydrous aluminum chloride are added slowly to 600 g of nitrobenzene, and the resulting solution is added to a solution of 80 g of phenanthrene in 240 g of nitrobenzene. The resulting solution is cooled in an ice bath, and 48 g of freshly distilled acetyl chloride is added in one portion. After 30 minutes in the ice bath and 6-7 hours standing at room temperature, the reaction mixture is poured into excess crushed ice containing 80 ml of hydrochloric acid. The combined product from five such runs is steam-distilled for removal of the nitrobenzene. The residue after removal of the nitrobenzene is distilled, and the fraction boiling in the range 180-214°/4 mm. pressure is collected. The distillate is digested with ether, the ethereal solution dried, and the solvent distilled off. The residue is recrystallized from methanol to give 315 g (65 %) of 3-acetylphenanthrene, m.p. 72°C. The solid material remaining undissolved during the ether digestion above is distilled twice at 2-3 mm. pressure, and the solid distillate is recrystallized from benzene. There is obtained 75 g. (15%) of the isomeric 2-acetylphenanthrene, m.p. 143°.
