Reaction Conditions

Reaction Steps

Anthraquinone (60 g) phenol (150 g) and 3-mercaptopropionic acid (8 g) were placed in a round-bottom flask. The mixture was heated at 65° C., and then dry hydrogen chloride was bubbled in for about 24 h. The phenol, hydrogen chloride, and cocatalyst were removed by steam distillation. This product was recrystallized from methanol as a slightly yellowish granular mass: MP 320°-322° C.
