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
• Toxic: Reaction products may be toxic

Nickel tetracarbonyl reacts vigorously with HNO3, releasing the toxic and flammable gas CO, and also producing nickel (II) nitrate. This reaction also likely produces flammable H2 gas (Atonsen, D.H., D.T. Meshri. 2005. Nickel Compounds. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

Dry 1,2-diaminoethanebis(trimethylgold) explodes on contact with even small amounts of nitric acid (Gilman, H. et al., J. Amer. Chem. Soc., 1948, 70, 550).

Tellurane-1,1-dioxide explodes violently on contact with nitric or sulfuric acids (Morgan, G. T. et al., J. Chem. Soc., 1928, 321).

Diphenyltin ignites on contact with HNO3 (Krause, E. et al. 1920. Berichte. 53:177).

Triphenyllead nitrate ignites on contact with concentrated sulfuric acid (Gilman, H. et al., J. Org. Chem., 1951, 16, 466).
