| Physical Description | Phosphorus pentafluoride is a colorless, poisonous, nonflammable, compressed gas with a pungent odor. It is extremely irritating to skin, eyes and mucus membranes. It is very toxic by inhalation and can cause pulmonary edema. Toxic and corrosive fumes are generated when this material is exposed to water or steam. Prolonged exposure of the containers to fire or heat may result in their violent rupturing and rocketing. It is used as a polymerization catalyst.Colorless gas with an unpleasant odor[HSDB] |

| Reactivity Profile | PHOSPHORUS PENTAFLUORIDE is a colorless, toxic gas, when exposed to air it strongly fumes. Vigorous reaction with water or steam leads to decomposition (hydrolysis) producing toxic and corrosive fumes. When heated to decomposition it emits toxic fumes of fluoride and oxides of phosphorus [Lewis, 3rd ed., 1993, p. 1034]. |
