Hazard Predictions

Inorganic cyanides are mild reducing agents. In combination with strongly oxidizing nitrate or nitrite salts, oxidation-reduction reactions are likely. Gases such as NOx may be evolved from the mixture and cause pressurization. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility. The generation of gases may be rather slow, however confinement may lead to dangerous conditions.

In general, nitrate and nitrite salts with redox active cations are more reactive with organic materials and reducing agents at ambient conditions. Redox active cations are transition metals and the metals in group 3a, 4a, and 5a of the periodic table and also include the ammonium cation NH4+. In general, nitrate and nitrite salts with non-redox active cations (also called spectator cations) are less reactive at ambient conditions. These include the alkali metals and alkaline earth salts. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.
