반응 단계
It has been known to produce benzanthrone by the following processes. (1) Anthraquinone is dissolved into sulfuric acid and a mixture of metallic powder and glycerin is added to the solution to reduce anthraquinone and simultaneously, the reaction product is further reacted with the compound resulted by dehydration of glycerin in an addition-reaction (B10S 987 and F1AT 1313). (2) Benzanthrone is produced by reacting an anthrahydroquinone ester such as acetate and sulfate which is obtained by reducing and esterifying anthraquinone, with acrolein in the presence of a dehydration catalyst such as sulfuric acid and piperidine in a solvent of acetic acid. (DRP 720,467). (3) Benzanthrone is produced by condensing α-benzoylnaphthalene at higher than 150° C. in the presence of aluminum chloride catalyst or at 120° C. in the presence of iron chloride catalyst. (DRP 239,761).
