Reaction Steps
2-chloro-4-nitro-phenol (64.44 g, 0.4 mole) and 300 ml 4M NaOH solution were refluxed with heating for 6 hours. After cooling down and filtration with vacuuming, the filtrate (crystal) was dissolved in a little warm water (60° C.). The solution was adjusted to pH 2.0 with 10% HCl and cooled down while stirring. After filtration, the filtrate was recrystallized with water to yield 4-nitro-1,2-benzenediol (52.1 g, yield rate 84%).
