1,2-萘醌-4-磺酸钠盐制备

1.不断搅拌下，将无水无色的１-氨基-２-萘酚-４-磺酸分次少量加到已冷至30℃的20%的稀硝酸中，每次加料必须充分搅拌，必要时可加适量乙醚消泡，并控制反应温度在20～25℃，加料结束后，将温度降至5～10℃，然后加入30℃的饱和氯化铵溶液，继续冷却至0℃，静置后过滤，结晶用少量冰冷的稀氯化铵溶液洗涤三次，再用乙醇洗涤二次，用乙醚洗涤数次，所得１-2-萘醌-４-磺酸在35～40℃干燥至恒重。然后用50℃的水溶解干燥的1-２-萘醌-４- 磺酸，加活性炭脱色。将30℃
的饱和氯化钠溶液加到过滤后的澄清桔色滤液中，静置冷却至０℃，滤出的结晶依次用稀氯化钠冷溶液、乙醇、乙醚洗涤至合格，并干燥至恒重，即得1,2-萘醌-４-磺酸钠。
