Reference
Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; p in Pa and T in Kelvin). The vapour pressure at 20°C was extrapolated from the vapour pressure curve to be 3.4 +/- 0.1 Pa.
Description of key information
The vapour pressure of the substance was determined in a GLP study according to test methods EC A.4 and OECD 104 to be 3.4 Pa at 20 °C, following the static technique (Van der Baan-Treur, 2003).
Key value for chemical safety assessment
- Vapour pressure:
- 3.4 Pa
- at the temperature of:
- 20 °C
Additional information
Recommended measurement range for the static technique is 10 to 10E5 Pa. In the current study, a capacitance manometer with a measuring range of 6x10E-3 to 2x10E5 Pa was applied extending the recommended measurement range to a lower limit of at least 10E-1 Pa as indicated in the test guideline.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
