Alm, Anita published the artcileMass spectra of diphenylamine compounds with nitro and nitroso substituents and of tetraphenylhydrazine, Related Products of catalysis-chemistry, the publication is Explosivstoffe (1969), 17(7), 156-64, database is CAplus.
During the decomposition of nitrocellulose in propellants, the oxides of N formed converted the stabilizer, Ph2NH, into a number of nitro and nitroso compounds, the nature and amounts of which are important in surveillance of the condition of the explosive. To assist in identification of the compounds of interest, the mass spectra of Ph2NH and 10 of its nitroso and nitro derivatives and that of N2Ph4 were determined and the spectra discussed with reference to characteristic peaks. The min. amounts required are important from a safety standpoint. A combination of thin-layer chromatog. and mass spectrometry in the anal. of mixtures in mg and ¦Ìg amounts is feasible.
Explosivstoffe published new progress about 1821-27-8. 1821-27-8 belongs to catalysis-chemistry, auxiliary class Nitro Compound,Amine,Benzene, name is Bis(4-nitrophenyl)amine, and the molecular formula is C12H9N3O4, Related Products of catalysis-chemistry.
