Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16 July 2013 - 23 August 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- (2009)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- (2006)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Version / remarks:
- (1996)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: isothermal thermogravimetry
- Remarks:
- (isothermal thermogravimetry)
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Test no.:
- #2
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The vapour pressure of the test substance at 25°C has been determined as < 2.2E-06 Pa (< 8.4E-07 Pa at 20°C) using the isothermal thermogravimetric effusion method (GLP-compliant study in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950).
Reference
The weight loss of the test substance at 170°C (second experiment), 180°C, 190°C and 200°C (both experiments) were lower than the weight loss of reference substance chrysene at the same temperatures. According to this the vapour pressure of the test substance was determined to be lower than that of chrysene.
Description of key information
The vapour pressure of the test substance at 25°C has been determined as < 2.2E-06 Pa (< 8.4E-07 Pa at 20°C) using the isothermal thermogravimetric effusion method (GLP-compliant study in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °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.
