Vapour pressure
Administrative data
Link to relevant study record(s)
Description of key information
The vapour pressure is very low and equals 0.48 Pa at 20 °C (Data from Roempp Encyclopedia). At higher temperature close to melting point, the vapour pressure is raised (see discussion)
Key value for chemical safety assessment
- Vapour pressure:
- 0.48 Pa
- at the temperature of:
- 20 °C
Additional information
Other reported data are:
NTP (National Toxicology Program (NTP) of the U.S. Department of Health and Human Services; 0.27 mm Hg at 25 °C
U.S. Environmental Protection Agency Office of Pollution Prevention and Toxics, and Syracuse Research Corporation (SRC)
Vapour Pressure Estimations (25 °C)(Using BP: 203.85 °C (estimated) and using MP: 31.50 °C (exp database)):
VP: 0.282 mm Hg (Antoine Method) = 37.6 Pa (Antoine Method)
VP: 0.239 mm Hg (Modified Grain Method) = 31.8 Pa (Modified Grain Method)
VP: 0.384 mm Hg (Mackay Method) = 51.2 Pa (Mackay Method)
Selected VP: 0.239 mm Hg (Modified Grain Method) = 31.8 Pa (Modified Grain Method)
Subcooled liquid VP: 0.273 mm Hg (25 °C, Mod-Grain method) = 36.4 Pa (25 deg C, Mod-Grain method)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
