HEEP COPYRIGHT: BIOL ABS. Several dinitroaniline compounds containing varying amounts of nitrosamines (known carcinogens) were treated with a variety of acids under different sets of conditions. HCl gas, HCl, and HBr were all effective at destorying the nitrosamines. H2SO4 efficiently removed nitrosamines without destruction, as the nitrosamines could be recovered from the neutralized acid extract. Other acids, e.g., ascorbic acid, phosphoric acid, p-toluenesulfonic acid and oxalic acid, were either considerably less effective or ineffective at removing nitrosamines from dinitroaniline compounds. Molecular Br, Cl gas, and N-bromosuccinimide are quite effective in lowering the nitrosamine levels to about 1 ppm of the nitrosamine contaminant.
