Stability and Reactivity
| Reactivity |
Reacts violently with nitric acid |
| Chemical stability |
Stable |
| Possibility of hazardous reactions |
Nitroaromatic (especially polynitroaromatic) compounds are seriously explosive if exposed to shock, sudden heating or uncontrolled fire; they may also decompose violently or explode if heated more gently with corrosive bases (even in the presence of water or organic solvents). |
| Conditions to avoid |
Heat, flames and sparks |
| Incompatible materials |
Strong oxidizing agents, strong reducing agents, strong bases |
| Hazardous decomposition products |
Carbon monoxide, carbon dioxide, nitrogen oxides |
