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
