METHOD OF OBTAINING PICRIC ACID |
| abstract |
The method for obtaining picric acid includes nitration of phenol nitro derivatives. O-nitrophenol and / or p-nitrophenol is nitrated to dinitrophenol in such a way that the resulting product is soluble in the reaction medium, and the nitration of dinitrophenol is continued until picric acid is obtained, which precipitates. |
