Process for the preparation of 5-nitro-3,4-dihydro-1(2H)-naphthalenone, 1,5-naphthalendiamine and 1,5-naphthalendiisocyanate |
摘要 |
A process for the production of 1,5-naphthalene diamine (I) comprises reaction of 4-(2-nitrophenyl)-n-butyronitrile to 4-(2-nitrophenyl)-n-butyric acid. Independent claims are included for: (1) a process for the production of 5-nitro-3,4-dihydro-1(2H)-naphthalinone by reaction of 4-(2-nitrophenyl)-n-butyronitrile to 4-(2-nitrophenyl)-n-butyric acid and; (2) a process for the production of 1,5-naphthalene diisocyanate by phosgenation of 1,5-naphthalene diamine (I).
