Formation of quinonediimines from phenylenediamines by catalytic oxidation |
| 摘要 |
A phenylenediamine compound can be converted, with high selectivity, into its corresponding quinonediimine by reacting the phenylenediamine with oxygen in the presence of a modified activated carbon catalyst in an aqueous system.
