실험 절차

135.5 g (0.5 mole) of 4-methoxycarbonylamino-anthrone in 1.5 liters of water are warmed to 70° C. After adding 50 ml of potassium water glass (d = 1.25), 400 ml of a hydrogen peroxide solution which contains 80 g per liter are added dropwise. The mixture is then stirred until the thin layer chromatogram of a sample which is withdrawn indicates the end of the reaction. In the course of the oxidation, the suspension has developed an intense reddish-tinged yellow color. The suspension is filtered and the product is washed until neutral and dried. 130.4 g (= 92.8%) of 1-methoxycarbonylamino-anthraquinone are obtained / melting point 214° C (from nitrobenzene).
