The present invention relates to a process for producing 5-nitro-3,4-dihydro-1(2H)-naphthalinone, 1,5-naphthalenediamine and 1,5-naphthalene diisocyanate, in which 4-(2-nitrophenyl)-n-butyronitrile is converted to 4-(2-nitrophenyl)-n-butyric acid.
本发明涉及一种生产5-硝基-3,4-二氢-1(2H)-
萘酮、
1,5-萘二胺和1,5-
萘二异氰酸酯的工艺,其中4-(2-
硝基苯基)-正
丁腈被转化为4-(2-
硝基苯基)-正
丁酸。
