STABILITY AND REACTIVITY
----------------------------------------------------------------------
Chemical Stability
Material is stable. However, avoid open flames and high
temperatures.
Incompatibility with Other Materials
Incompatible with alkali or alkaline earth metals--powdered
Al, Zn, Be, etc.
Decomposition
Decomposition products are hazardous. "FREON" 22 can be
decomposed by high temperatures (open flames, glowing metal
surfaces, etc.) forming hydrochloric and hydrofluoric acids,
and possibly carbonyl halides. These materials are toxic
and irritating. Contact should be avoided.
Polymerization
Polymerization will not occur.
