Process for producing 1,5-diaminonaphthalene |
| abstract |
The present invention relates to a process for producing 1,5-diaminonaphthalene without formation of 1,8-diaminonaphthalene and not through an unstable nitro imine and nitro enamine as intermediates, the process including the steps of dehydrogenating 5-substituted-1-tetralone to produce a naphthol compound and then aminating the hydroxyl group of the naphthol compound. |
