Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The extrapolated vapor pressure of 138492 at 20ºC is 4 x 10-26 torr (9 x 10-27 kPa, 8 x 10-28 PSI).

Executive summary:

The extrapolated vapor pressure of 138492 at 20ºC is 4 x 10-26torr (9 x 10-27kPa, 8 x 10-28PSI).

 

Description of key information

The extrapolated vapor pressure at 20ºC is 4 x 10-26 torr (9 x 10-27 kPa, 8 x 10-28 PSI). The value used for the CSA is 1E-6 Pa as this is the minium value for the exposure assessment models using ECETOC TRA.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C
