反応手順
34.6 g (100 mmol) of dipotassium 2,5-dihydroxybenzene-1,4-disulfonate were dissolved in 500 ml of water at 60° C. After addition of 0.68 g (2 mmol) of iron 5,14-dihydrodibenzo[b,i][5,9,14,18]-tetraaza[14]annulene, 0.8 g (2 mmol) of diethylenetriaminepentaacetic acid, 1 ml of concentrated sulfuric acid and 1 ml of a commercial antifoam agent, 28.4 g (250 mmol) of 30% by weight aqueous hydrogen peroxide were added dropwise. The mixture was stirred for 15 min at 60° C. The solution was cooled to 5°-10° C. and then the solid was filtered off with suction and recrystallized from water to yield 14.5 g (42%) of dipotassium 1,4-benzoquinone-2,5-disulfonate in the form of reddish brown needles. Melting point >360° C.
