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:
- From 1998-11-13 to 1999-03-03
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- OJ No. L383A, 29.12.92
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Specific details on test material used for the study:
- Batch No.: 960509
Purity: 92.3% - Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.001 Pa
- Remarks on result:
- other: mean od four runs
- Conclusions:
- The vapour pressure of test item is 5.0 E-4 Pa at 25 ℃.
- Executive summary:
The vapour pressure was determined using a vapour pressure balance based on OECD 104 and EC A4.
The vapour pressure of test item is 5.0 E-4 Pa at 25 ℃.
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- Vapour pressure is expected to be very low, given the boiling point is over 200°C and the material will only be used in a chemical plant, either during manufacture or when used as an intermediate. It is therefore reasonable to use a well-established calculation method to estimate the property.
- Principles of method if other than guideline:
- The vapour pressure was estimated using the EPI Suite software provided by the US EPA, version 4.11, calculated by Modified Grain method.
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 Pa
- Conclusions:
- The vapour pressure of the substance is estimated to be 0.00035 Pa at 25°C
While the accuracy is uncertain, this figure is considered good enough for the purposes of evaluating inhalation toxicity. - Executive summary:
The vapour pressure of the substance is estimated to be 0.00035 Pa at 25°C using the EPI Suite software provided by the US EPA, version 4.11, calculated by Modified Grain method.
