Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Vapour pressure of the liquid substance: 0.000064 hPa at 70 °C (OECD 104)
Vapour pressure of the solid substance: 0.0000053 Pa at 20 °C (estimated, OECD 104)

Key value for chemical safety assessment

Vapour pressure:
0 hPa
at the temperature of:
70 °C

Additional information

Above the melting point of the test substance the vapour pressures were measured. Below the melting point of the substance the vapour pressure was below the detection limit, therefore an extrapolation was made from the liquid range to room temperature with the help of the Anoine equation to obtain an upper limit for the vapour pressure of the solid test substance.
