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:
- 25.11.2011 - 9.02.2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study was performed under GLP conditions in accordance with OECD guideline
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 Pa
- Remarks on result:
- other: extrapolated value
- Conclusions:
- The vapour pressure of the test item has been determined to be 1.2 x 10-4 Pa at 25 °C.
- Executive summary:
The vapour pressure was determined according to OECD TG 104 to be 1.2 x 10-4 Pa at 25 °C. Measurements were made at several temperatures using a vapour pressure balance. The vapour pressure at 25 °C was extrapolated from the measurements using linear regression analysis.
Reference
Main sequence
A total of ten runs were completed for the main sequence. Equilibrium with regard to vapour pressure was assessed to have been reached over the final five runs. Thus the final five runs have been used to calculate the definitive vapour pressure value for the test item.
