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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables
The vapour pressure was measured in the temperature range of 20 °C to 150 °C. In the temperature range 20 °C up to 106 °C no increase in weight and therefore no vapour pressure of the test substance was registered . Up to about 90 °C the test substance had melted, so the vapour pressure curve was restricted an the values between 1.1E-5 and 5.6E-4 hPa, i .e. between 112 °C and 150 °C. The values for 20, 25 and 50°C are calculated using the Antoine constants.
Applicant's summary and conclusion
- Conclusions:
- The extrapolated vapour pressure value for 25°C is 4.8E-11 hPa.
- Executive summary:
Based on the measured data by using the effusion method (vapour pressure balance), the extrapolated vapour pressure value for 25°C is 4.8E-11 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
