実験手順

Various portions of the 1-chloro-2,6-dinitro-4-(trifluoromethyl)benzene (treated as described above) were aminated with N-n-butyl-N-ethylamine, to produce N-n-butyl-N-ethyl-2,6-dinitro-4-(trifluoromethyl)aniline, or with N-ethyl-N-methallylamine, to produce N-ethyl-N-methallyl-2,6-dinitro-4-(trifluoromethyl)aniline. Each product was analyzed for nitrosamine content. The N-n-butyl-N-ethyl-2,6-dinitro-4-(trifluoromethyl)aniline was found to contain 7 or 20 ppm of N-nitroso-N-n-butyl-N-ethylamine (two different analytical laboratories) and the N-ethyl-N-methallyl-2,6-dinitro-4-(trifluoromethyl)aniline was found to contain 16 ppm of N-nitroso-N-ethyl-N-methallylamine.
