- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- between 07 January 2009 and 17 April 2009.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Date of inspection: 19th August 2008 Date of signature: 4th March 2009
- Type of method:
- effusion method: vapour pressure balance
- Key result
- Temp.:
- 25 °C
- Vapour pressure:

- Remarks on result:
- other: extrapolated
- Conclusions:
- The vapour pressure of the test material has been determined to be 8.8 x 10-10 Pa at 25 ºC using a vapour pressure balance.
A vapour pressure of 6.2E-06 Pa at 80 °C can be extrapolated based on the raw data of the study by the applicant. - Executive summary:
Vapour Pressure.
The vapour pressure has been determined to be 8.8 x 10-10 Pa at 25 ºC, using a vapour pressure balance, Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
Based on the raw data of the study a vapour pressure of 6.2E-06 Pa at 80 °C can be extrapolated.
Reference
A total of 7 runs were undertaken, the table below shows the results for each run and the vapour pressure was worked out as an average based on all of these runs.

Description of key information
The vapour pressure of the substance was determined as 8.8E-10 Pa at 25 °C (298 K) according to OECD Guideline 104 using the effusion method (vapour pressure balance). The vapour pressure at 298 K was extrapolated from the vapour pressure curve.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
Testing was started after the sample had been under vacuum for approximately 44.5 hours. Temperature and pressure readings were taken between 160 and 170 °C with a one hour dwell at 160°C between runs. Based on the average result of seven runs, the vapour pressure of the substance was determined to be 8.8E-10 Pa at 25 °C (298 K).
A vapour pressure of 6.2E-06 Pa at 80 °C can be extrapolated based on the raw data of the study.
