Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 5 October 2006 - 12 January 2007
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- October 2002
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- December 1992
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: isothermal thermogravimetry
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure. The vapour pressure at 20°C (293K) was < 8.40·10-7 Pa = < 6.30·10-9 mm Hg.
- Executive summary:
Representative weight loss curves of the test substance and the reference substance chrysene were plotted. The weight loss of the test substance at 170°C was lower than the weight loss of chrysene at the same temperature. From this, it was concluded that the vapour pressure of the test substance is < 8.40·10 -7 Pa = < 6.30·10 -9 mm Hg.

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.
