Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- the experimental determination was not possible due to the nature of the substance.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- yes
- Remarks:
- the experimental determination was not possible due to the nature of the substance.
- Principles of method if other than guideline:
- Based on experience with a similar substance it was concluded that the experimental determination of the vapor preassure of EMCA is not possible due to the corrosive nature of acid chlorides on the analytical equipment.
As an alternative, the modified Watson correlation calculation method for the vapor pressure was used. - GLP compliance:
- yes (incl. QA statement)
- Key result
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 176 Pa
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- determined by calculation.
- Conclusions:
- Using the modified Watson correlation calculation method with boiling point as experimental value (183ºC), the vapor pressure of the test subtance at 25ºC was calculated to be 176 Pa (1.32 mm Hg).
- Executive summary:
Based on experience with a similar substance it was concluded that the experimental determination of the vapor pressure of the test item is not possible due to the corrosive nature of acid chlorides on the analytical equipment. As an alternative, the modified Watson correlation calculation method for the vapor pressure was used. By using the modified Watson correlation calculation method with boiling point as experimental starting value (183ºC), the vapor pressure of the test subtance at 25ºC was calculated to be 176 Pa (1.32 mm Hg).
