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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Vapour pressure
- Temp.:
- 70 °C
- Vapour pressure:
- 1.26 hPa
- Remarks on result:
- other: extrapolation on the basis of experimental data is not valid for values <70°C, because in the temperature range used for the vapour pressure measurements the test substance was liquid.
Any other information on results incl. tables
Regression of the vapour pressure data (mean deviation 0.23 %): ln (p/hPa) = 11.0128 -6220.11/ (182.88 + t/°C)
In the temperature range used for the vapour pressure measurements the test substance was liquid.

Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
