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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Test no.:
- #1
- Temp.:
- >= 20 °C
- Vapour pressure:
- >= 0.007 - <= 7.6 Pa
- Remarks on result:
- other: Values below melting point
- Key result
- Test no.:
- #2
- Temp.:
- >= 25 °C
- Vapour pressure:
- >= 0.012 - <= 12 Pa
- Remarks on result:
- other: Values below melting point
Reference
Since no accurate vapour pressure could be calculated from the obtained results below the melting point, the weight losses of the test item were compared with the results of Naphthalene at 50°C.
Since the weight loss of the test item was lower than the weight loss of
the reference compound, the vapour pressure of the componds is
considered to be below the vapour pressure of Naphthalene.
Conclusion (details see file attach under key result).
Description of key information
Since no accurate vapour pressure could be calculated from the obtained results below the melting point, the weight losses of the test item were compared with the results of Naphthalene at 50°C.
Since the weight loss of the test item was lower than the weight loss of the reference compound, the vapour pressure of the componds is considered to be below the vapour pressure of Naphthalene.
Key value for chemical safety assessment
- Vapour pressure:
- 0.007 Pa
- at the temperature of:
- 20 °C
Additional information
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.
