Reaktionsschritte

With respect to 1 kg of the reaction solution generated in synthesis example 1, 1 L of toluene and 2 L of water were added. These components were stirred for 5 minutes and extraction was conducted. Then, the resultant substance was kept still for 15 to 20 minutes to be separated, and the upper toluene layer was recovered. The above-extracted solution and the same amount of 4% aqueous solution of sodium hydroxide were put into a separatory funnel, shaken and kept still. Then, the lower black liquid was removed. The remaining liquid was washed with water of the same amount as that of the remaining liquid. Then, the lower layer was removed. Water was added, 2 mL of hydrochloric acid was added, and these components were shaken. The lower layer was removed, and the remaining substance was washed with water again. The oil layer was washed with an alkaline substance and concentrated to remove the solvent. The concentrate was distilled at a pressure of 1 to 2 mmHg. As a result, 16 g of acenaphthene-1-one was obtained at a distillation temperature of 120° C.
