Method for purifying halogenoaminophenol |
| abstract |
(57) [Summary] [Object] To provide a method for purifying halogenoaminophenol, which can prevent coloring by purifying halogenoaminophenol by a simple method that does not require a long time for purification and stabilization. [Structure] The halogenoaminophenol obtained by reduction of the halogenonitrophenol or its ammonium salt is dissolved in water, brought into contact with an adsorbent, and then a reducing agent is added to crystallize the halogenoaminophenol. A method for purifying halogenoaminophenol, which is characterized. |
