Hydrochloric Acid → Pyrogallol
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | Pyrogallol triacetate | HCID 10678 | — |
| Solvent | Acetic Acid | HCID 176 | — |
| Product | Pyrogallol | HCID 1057 | 87% |
Reaction Steps
To 100 parts of pyrogallol triacetate as prepared above were added glacial acetic acid (364 parts) and 2 N HCl solution (3640 parts) and the mixture refluxed for three hours under a nitrogen blanket. Continuous ether extraction followed by evaporation of the extract gave an oil which slowly crystallised. Recrystallisation from toluene gave pyrogallol (44 parts, 87% yield).
