Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From June 30, 1999 to October 05, 1999
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 hPa
- Remarks on result:
- not determinable because of methodological limitations
- Transition / decomposition:
- yes
- Transition temp.:
- >= 100 - <= 340 °C
- Conclusions:
- Under the test conditions, the vapour pressure value of the test substance is below 1x10(-5) hPa (lower measuring limit) at 25 °C.
- Executive summary:
A study was performed to determine the vapour pressure of test substance according to EU Method A.4. in compliance with GLP.
Vapour pressure balance
The test substance was degassed (volatile components are removed) by treating under vacuum (approx. 10-2 hPa) over night at room temperature before the measurement.
The quantity of substance leaving a cell per unit time through an aperture of known size was determined under vacuum conditions such that return of substance into the cell is negligible (e.g. by measurement of the pulse generated on a sensitive balance by a vapour jet or by
measuring the weight loss).
Recommended range: 10-5 to 10-2 hPa, between 0 and 150 °C.
As a precaution a Differential Scanning Calorimetry was performed. Two measurements in a closed glass pan does not show any endothermic effect prior an exothermal decomposition was observed in the range 100-340 °C, with a decomposition energy of 691 J/g respectively 636 J/g. Therefore the maximum temperature of the measurement was limited to about 80 °C. No increase in weight and therefore no vapour pressure of the test substance was registered with the balance in the temperature range between 21 and 81 °C.
The vapour pressure of the test substance was up to 81 °C below the lower measuring limit of the vapour pressure balance.
The vapour pressure value for 25 °C is below 1x10-5 hPa (lower measuring limit).
