Process for the preparation of picric acid |
| abstract |
In the process according to the invention, the orthonitrophenol and / or the para-nitrophenol are converted to the dinitrophenol or phenols by nitration in such a way that the one or more intermediates formed remain in solution and then the one or more dinitrophenols. -phenol nitration is continued and excellent picric acid is recovered in the form of a precipitate. ŕ |
