Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Polymerization hazard: Polymerization reaction may become intense and may cause pressurization

Nitriles can be reduced by alkali metal amalgams, forming reactive radical intermediates. In the presence of a proton source, amines are produced (Cartolano, A. R. and Vedage, G. A. 2004. Amines by Reduction. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).

Reaction between lithium and acetonitrile is exothermic (Ebner, W.B. et al. 1982. Proceedings from the 8th Power Sources Symposium. pp. 119-124).

Acetonitrile is incompatible with group I metals (Lenga, R.E., ed. 1988. Sigma Aldrich Library of Chemical Safety Data, 2nd Edition. Sigma Aldrich. pp. 21).

Rapid polymerization of acrylonitrile can be initiated by free radicals, such as alkali metals (Bradzil, J. F. 2010. Acrylonitrile. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
