Hazard Predictions

• Potentially hazardous: May be hazardous but unknown

When combined, strong oxidizers and nitriles may react with intensity, as shown in the examples below. However, no specific evidence was found for a hazardous reaction between weak oxidizers and nitriles. 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.

Reaction of acetonitrile with perchlorates is violent and may accelerate to explosion (Fosberg, J.H. 1984. Chemical and Engineering News 62960, 33; Bancroft, G.M., et al. 1974. Canadian Journal of Chemistry 52:783; Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 24.), as may reactions of acetonitrile and N2O4 (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 1689).

Acrylonitrile undergoes explosive polymerization with AgNO3 after an induction period, and may ignite (Association of British Chemical Manufacturers. 1962. Quarterly Safety Summary 23, 33; Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 69).
