Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | P-Phenylenediamine | HCID 7814 | — |
| Reactant | 2-Naphthol | HCID 8663 | — |
| Product | 2-Naphthylamine | HCID 7057 | 94% |
Reaction Steps
In another run using a molar ratio of 4:1 of β-naphthol to p-phenylenediamine with 3% B2O3, based on the weight of β-naphthol, at 200° C., and a reaction time of 4 hours, a 94% yield was obtained with only 6 ppm β-naphthylamine being formed.
