CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Phenyl phosphine is a clear colorless liquid. (NTP, 1992) |
|---|---|
| Color/Form | Clear, colorless liquid |
| Odor | Foul odor |
| Boiling Point | 320 to 322 °F at 760 mmHg (NTP, 1992) |
| Solubility | less than 1 mg/mL at 70 °F (NTP, 1992) |
| Density | 1.001 at 59 °F (NTP, 1992) - Denser than water; will sink |
| Vapor Density | 3.79 (NTP, 1992) - Heavier than air; will sink (Relative to Air) |
| Vapor Pressure | 2.45 [mmHg] |
| LogP | log Kow = 1.49 /Estimated/ |
| Henry's Law Constant | Henry's Law constant = 2.38X10-4 atm-cu m/mol @ 25 °C /Estimated/ |
| Decomposition | The substance decomposes on heating producing toxic fumes including phosphorous oxides and phosphine. |
| Odor Threshold | Concentrations of 0.57 ppm (2.6 mg/cu m) were readily detected by an odor panel; the odor was experienced as obnoxious. As lower concentration were not evaluated, an odor threshold was not established. |
| Other Experimental Properties | Spontaneously combustible in high concentrations in air. Potential exposure to gaseous phenylphosphine when polyphosphinates are heated above 200 °C |
| Chemical Classes | Other Classes -> Phosphorus Compounds |
