Versuchsvorschrift

A three necked flask having a capacity of 300 ml and equipped with a stirrer, a thermometer, a heating jacket and a charge inlet, 32 g of a 30% sodium hydroxide aqueous solution and 57 g of water were charged, and with stirring, 25 g of 9,10-anthracenedione was charged and suspended, whereupon air in the flask was substituted by nitrogen. While stirring the content in this flask, 130 g of an aqueous solution of a sodium salt of 1,4-dihydro-9,10-dihydroxyanthracene (22% as the concentration of anthracenedione) was added, and the mixture was maintained at an internal temperature within a range of from 85 to 90° C. for 4 hours to obtain an aqueous solution of a sodium salt of 9,10-anthracenediol.
