Preparation of Benzanthrone: it is prepared by reaction of anthracenequinone with glycerol. Firstly, anthracenequinone is reducted with iron to generate hydroxy-anthrone. Meanwhile, glycerol reacts with concentrated sulfuric acid to get acrolein. Secondly, hydroxy anthraquinone is mixed with acrolein with the presence of sulfuric acid to form new ring. At last, product is obtained by oxidation with sulfuric acid.
Uses of Benzanthrone: it is used to produce 3-nitro-benz[de]anthracen-7-one. The reaction needs reagent 88% nitric acid and solvent nitrobenzene at the temperature of 50 °C for 3 hours. The yield is about 74.6%.
