Nitric Acid → 1,5-Diaminonaphthalene

Participants

Reaction Steps

The invention also provides a process for the production of 1,5-diisocyanatonaphthalene in which naphthalene and/or 1-nitronaphthalene is reacted with nitric acid in the presence of a zeolite, the resulting 1,5-dinitronaphthalene is then hydrogenated to form 1,5-diaminonaphthalene and the resulting 1,5-diaminonaphthalene is phosgenated to form 1,5-diisocyanatonaphthalene.
