CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Phosphorus pentachloride is a greenish-yellow crystalline solid with an irritating odor. It is decomposed by water to form hydrochloric and phosphoric acid and heat. This heat may be sufficient to ignite surrounding combustible material. It is corrosive to metals and tissue. Long term exposure to low concentrations or short term exposure to high concentrations can result in adverse health effects from inhalation. |
|---|---|
| Color/Form | White to pale yellow crystalline mass |
| Odor | Pungent, unpleasant odor |
| Boiling Point | 320 °F at 760 mmHg (EPA, 1998) |
| Melting Point | (decomposes) 298 °F (under pressure) sublimes at about 212 °F without melting (EPA, 1998) |
| Solubility | Reacts with water (NIOSH, 2023) |
| Density | 3.6 (NIOSH, 2023) - Denser than water; will sink |
| Vapor Density | 7.2 (Air = 1) |
| Vapor Pressure | 1 mmHg at 131.9 °F (EPA, 1998) |
| Decomposition | PRODUCES PHOSPHORUS TRICHLORIDE & CHLORINE WHEN HEATED; PRODUCES PHOSPHORUS OXYCHLORIDE, PHOSPHORIC ACID, & HYDROCHLORIC ACID WHEN DECOMPOSED IN WATER |
| Corrosivity | Corrosive |
| Heat of Vaporization | 64.9 kJ/mol |
| Other Experimental Properties | Deliquescent; reacts with alcohols to form corresponding chloride |
| Chemical Classes | Toxic Gases & Vapors -> Other Toxic Gases & Vapors |
