SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride and phosphorus oxides. Reacts violently with water. This produces heat and decomposition products including hydrochloric acid and phosphoric acid. This generates fire and explosion hazard. Reacts violently with alcohols, phenols, amines and many other materials.
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
PRODUCTS OF ITS REACTION WITH WATER RAPIDLY CORRODE STEEL & MOST METALS WITH FORMATION OF FLAMMABLE HYDROGEN GAS.The vapour is heavier than air.PHOSPHORUS OXYCHLORIDE is water reactive. Incompatible with strong oxidizing agents, alcohols, bases (including amines). 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]. Combining the chloride with zinc dust caused immediate ignition, due to the formation of phosphine gas which ignites, [Mellor, 1940, Vol. 8, 1025]. An exotherm starting with the mixing of phosphorus oxychloride with acetone (a ketone) lead to an explosion, may behave similarly with other ketones, [Organic Process Research and Development, Vol.4, No. 6,200, "Phosphorus Oxychloride and Acetone: An Incompatibility Investigation Using ARC."]
10.4 Conditions to avoid
no data available

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.Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
