Decomposes on heating and on burning. This produces toxic fumes of nitrogen oxides.
10.2 Chemical stability
Does not react with plasticizers and other components of plastics.
10.3 Possibility of hazardous reactions
FlammableAZODICARBONAMIDE is easily ignited and burns rapidly. Confined samples show a high rate of pressure rise during thermal decomposition, which produces carbon monoxide and nitrogen. Sensitive to temperatures exceeding 122°F. May be sensitive to exposure to light. Stable in bulk when stored for two weeks at temperatures up to 140° F. Slightly unstable in water suspension (showed 1.3% decomposition at 2 mg/mL over a two-week period at room temperature in the light but no decomposition at 41° F over a two-week period in the dark (NTP, 1992). Reacts with hot water to give nitrogen, carbon monoxide, and ammonia [Hawley]. Decomposes in hot hydrochloric acid. Incompatible with strong acids and bases, and with compounds of metals.
