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)
• Toxic: Reaction products may be toxic

If the nitride is soluble in the nitrile compound, it can extract the alpha-hydrogen from the nitrile (i.e. hydrogen atoms on the carbon adjacent to the nitrile carbon atom) to form flammable ammonia gas. Some heat can be evolved (Rich, G. A., 1993, Dangerous Chemical Reactions, Gulf Publishing Co., Houston, TX, p. 288).

Phosphides, carbides, and silicides are predicted to behave similarly to nitrides, therefore they are predicted to deprotonate nitriles, generating PH3, CH4, and SiH4, respectively. These products are flammable gases, and phosphine and silane are also toxic.

Potential Gas Byproducts

• Hydrocarbons
• Ammonia (NH3)
• Phosphine (PH3)
• Silanes
