Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

The product is chemically stable under standard ambient conditions (room temperature).

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.

Hazardous reactions

Risk of explosion with: silver salt; Exothermic reaction with: alkalines, alkali hydroxides, Amines; Violent reactions possible with: Strong oxidizing agents, sulfoxides, dimethyl sulfoxide, with Copper

Avoid

Exposure to moisture, Heat, Strong heating.
