Conclusions.-o-Aminophenol and its derivatives are unstable in the presence of a strong oxidizing agent such as fuming nitric acid, o-aminophenol itself going to pieces. p- Aminophenol is capable of giving a good yield of nitro-aminophenolsulfonic acid under the conditions holding in our work. Assuming the most stable configuration of the benzene ring to be that in which alternate carbons are similarly polarized, an electronegative group can ...
