Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 22.01.-15.03.2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- no
- Type of method:
- effusion method: Knudsen cell
- Key result
- Temp.:
- 90 °C
- Vapour pressure:
- 0.004 Pa
- Remarks on result:
- other: derived limit value
- Remarks:
- No temperatures up to 150 °C could be evaluated with reproducible or relevant weight loss. As a calculation on base of the measured weight losses is not possible, the highest mean vapour pressure, derived from all measurements, is stated as limit value.
- Conclusions:
- No temperatures up to 150 °C could be evaluated with reproducible or relevant weight loss. As a calculation on base of the measured weight losses is not possible, the highest mean vapour pressure, derived from all measurements, is stated as limit value.
Vapour pressure at 90°C: 0.00412 Pa
Reference
Test Item
Vapour pressure was examined at nine different temperatures (at 30, 45, 60, 75, 90, 105, 120, 135 and 150°C). No temperatures could be evaluated as they showed no reproducible or relevant weight loss.
As a calculation on base of the measured weight losses is not possible, the highest mean vapour pressure, derived from all measurements, is stated as limit value.
Vapour pressure at 90°C: 4.12* 10-03 Pa
Positive Control
For Diethylphthalate the following vapour pressure was determined and compared with recommended value:
Table 10.2-a Results Positive Control
Vapour pressure (positive control) at 30°C: |
1.60*10-1 Pa |
Criterion for the vapour pressure of the positive control at 30°C |
0.44*10-1- 2.44*10-1 Pa |
The vapour pressure met the validity criteria. Therefore, the study can be considered as valid.
Description of key information
The vapor pressure was tested according to the OECD Guideline 104 (effusion method: Knudsen cell) at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss. As
a calculation on base of the measured weight losses is not possible, the highest mean vapour pressure, derived from all measurements, is stated as limit value.
Vapour pressure at 90°C: 4.12* 10-03 Pa
Key value for chemical safety assessment
- Vapour pressure:
- 0.004 Pa
- at the temperature of:
- 90 °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.
