Nitric Acid → 1-Nitroanthraquinone
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Nitric Acid | HCID 944 | — |
| Reactant | Anthraquinone | HCID 6780 | — |
| Product | 1-Nitroanthraquinone | HCID 6704 | 74.5% |
Reaction Steps
German Offenlegungsschrift (German Published Specification) 2,162,538 describes the nitration of anthraquinone in nitric acid, of concentrations exceeding 90%, the molar ratio of anthraquinone to nitric acid being at least 1:20. A part of the by-products can be removed by diluting the acid with water, so that 1-nitroanthraquinone is obtained in 74.5% yield, but its purity does not exceed 92%.
