Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key result
Temp.:
20 °C
Vapour pressure:
0.17 mBar
Remarks on result:
other: The result is the mean of 2 runs.

Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; p in mbar and T in Kelvin). The temperature range was 39.9 °C-103.7°C and 40.7 -101.0°C for run 1 and run 2, respectively. The vapour pressure extrapolated to 20°C was 0.16 mbar (run 1) and 0.18 mbar (run 2).

Conclusions:
The vapour pressure of the substance was extrapolated from the vapour pressure curve to be 0.17 mbar (17 Pa) at 20°C.

Description of key information

The vapour pressure of the substance was determined in a GLP study according to test method EC A.4 to be 17 Pa at 20 °C, following the static technique (Younis S, 2012).

Key value for chemical safety assessment

Vapour pressure:
17 Pa
