SECTION 10: Stability and reactivity

10.1 Reactivity

Decomposes on heating and on contact with water. This produces toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. Reacts violently with strong oxidants. Attacks metals. The substance is a strong oxidant. It reacts with combustible and reducing materials.

10.2 Chemical stability

no data available

10.3 Possibility of hazardous reactions

PRE-ADDITION OF NITROGEN OXIDE (OR NITROSYL CHLORIDE AS ITS PRECURSOR) TO STOICHIOMETRIC HYDROGEN-OXYGEN MIXT @ 240 MBAR/360 DEG C WILL CAUSE IMMEDIATE IGNITION UNDER VARIETY OF CIRCUMSTANCES.The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.NITROSYL CHLORIDE is an oxidizing agent. Dissociates into nitric oxide and chlorine on heating. Gives an explosive reaction when sealed in a tube with a residue of acetone and in the presence of platinum catalyst [Chem. Eng. News 35(43):60. 1967]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Other Information

Reacts violently with fire extinguishing agents such as water.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.Rinse contaminated clothing with plenty of water because of fire hazard.Check oxygen content before entering area.High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
