Stability and Reactivity
Reactivity:
Forms explosive mixtures with air on intense heating. A range from approx. 15 Kelvin below the flash point is to be rated as critical. The following applies in general to flammable organic substances and mixtures: in correspondingly fine distribution, when whirled up a dust explosion potential may generally be assumed.

The product is chemically stable under standard ambient conditions (room temperature) .
Possibility of hazardous reactions:
Risk of explosion with:
Nitric acid
Risk of ignition or formation of inflammable gases or vapours with:
mineral acids
Acids
Conditions to avoid:
Strong heating.
Incompatible materials:
various plastics
Hazardous decomposition products:
