Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 9,10-Anthracenedione, 1,2-dinitro- | HCID 42596 | — |
| Reactant | 1,8-Dinitro-9,10-anthraquinone | HCID 67210 | — |
| Solvent | Nitric Acid | HCID 944 | — |
| Product | 9,10-Anthracenedione, 1,5-dinitro- | HCID 6705 | — |
Reaction Steps
y<50: Nitric acid ratio in the mixed acid is too low, where leaching of dinitroanthraquinone isomers soluble in nitric acid, including 1,8-dinitroanthraquinone, is not sufficient thus failing to obtain 1,5-dinitroanthraquinone of a high purity.
