Preparation of 9,10-phenanthrenequinone
Alternative Names: Phenanthrene-9,10-dione; Phenanthrenequinone; 9,10-Phenanthraquinone; 84-11-7; Phenanthraquinone;
30 g phenanthrene are dissolved in the heat in 120 g acetic acid, and a solution of 70 g chromic acid in about 200 g strong acetic acid is gradually added. This latter solution is prepared by dissolving the chromic acid in a very little water, and then pouring the aqueous solution into glacial acetic acid. The mixture gets warm spontaneously, and it is easy so to carry out the operation that the temperature remains approximately at the boiling point of the acetic acid. Finally most of the acetic acid is distilled off and the residue is then treated with water. The reddishyellow crystalline mass precipitated, which contains the 9,10-phenanthrenequinone along with some unchanged phenanthrene, is filtered and washed with a little hot water. To purify the crude 9,10-phenanthrenequinone it is treated in the warm with a dilute solution of sodium bisulfite; the filtrate is warmed on the water-bath, and the 9,10-phenanthrenequinone precipitated by acidifying with sulfuric acid. This product is then recrystallized from a large quantity of boiling alcohol.
