SECTION 10: Stability and reactivity
Reactivity
Decomposes above 350°C . This produces toxic fumes including nitrogen oxides and hydrogen cyanide. Reacts violently with water, moist air, carbon dioxide, acids and acid salts. This produces highly toxic and flammable hydrogen cyanide. Reacts violently with oxidizing substances when heated. This generates fire and explosion hazard.
Chemical stability
no data available
Possibility of hazardous reactions
Not flammableCALCIUM CYANIDE gives weakly acidic solutions. Contact with acids causes rapid evolution of hydrogen cyanide. Incompatible with isocyanates, nitrides, and peroxides. May react rapidly with oxidizing agents.
Conditions to avoid
no data available
Incompatible materials
Reacts with water and acids evolving highly toxic hydrogen cyanide.
Hazardous decomposition products
Calcium cyanide is/ ... readily hydrolyzed liberating hydrogen cyanide.
