Hazard Predictions

• Potentially hazardous: May be hazardous but unknown

When combined, strong oxidizers and organic nitro compounds may react with intensity, as shown in the examples below. However, no specific evidence was found for a hazardous reaction between weak oxidizers and organic nitro compounds. Because of the nature of the members of the Weak Oxidizing Agents group we would not expect reaction kinetics to yield hazardous conditions. We urge chemists to perform testing to ensure that hazards do not occur under conditions appropriate to the scenario.

Nitrobenzene forms explosive mixtures with N2O4 and other oxidizing agents (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 2518; Urbanski, T., 1967, Chemistry and Technology of Explosives, London, MacMillan, Vol. 3, p. 288; Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 1289).

Nitrobenzene forms explosive salts with AgNO3 (Luchs, J.K. 1966. Photog. Sci. Eng. 10:336).

Nitromethane reacts violently with Ca(OCl)2 and other oxidants (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 2544).

Ethyl nitrate reacts violently with strong oxidants (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 1643).

Metal oxides may cause violent decomposition of aliphatic nitro compounds (Markofsky, S.B. 2002. Nitro Compounds, Aliphatic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).

Nitromethane is sensitized by oxidizing agents, including metal oxides (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 2544, 3426; Hermoni, A. et al. 1960. Chemistry and Industry 1265).

Sodium chlorate and nitrobenzene is an explosive combination that has been used in numerous terrorist bombings (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 1289).

Mixtures of nitromethane and heavy metal oxides, such as those of silver, lead, and mercury, can lead to violent decompositions and should be avoided (Markofsky, S. B. 2000. Nitro Compounds, Aliphatic. Ullmann's Encyclopedia of Industrial Chemistry).
