Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
Stable under normal temperatures and pressures.
Conditions to Avoid:
Incompatible materials.
Incompatibilities with Other Materials:
Incompatabilities with sodium chloride include: most nonoble metals such as iron or steel, building materials ( such as cement), bromine, or trifluoride. Sodium chloride is potentially explosive with dichloromaleic anhydride + urea. Electrolysis of mixtures with nitrogen compounds may form explosive nitrogen trichloride.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide.
Hazardous Polymerization:
Stable under normal temperatures and pressures.
Conditions to Avoid:
Incompatible materials.
