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:
- 01 December 1998 to 02 December 1998
- 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
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 hPa
- Conclusions:
- The vapour pressure value for 25 °C is lower than 10-5 hPa.
- Executive summary:
The purpose of the test was the determination of the vapour pressure according to Guideline 92/69/EEC Part A.4.Vapour pressure using theVapour pressure balance method. Study conducted in compliance with GLP.
The quantity of substance leaving the cell per time unit through an aperture of known size is determined under vacuum conditions. Due to the conditions of measurement the 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: 10-5to 10-2hPa, between 0 and 150 °C
For precaution information to the thermal stability a Differential Scanning Calorimetry of the test substance was performed (see project SI094-98). The measurement in a closed glass pan shows an exothermal effect beginning at 175°C.
The vapour pressure was first measured at a temperature of 20⁰C. At 143 °C the vapour pressure of the test substance was above the lower measuring limit.
At 150 °C the measuring was stopped, because at higher temperatures a thermal decomposition of the test substance was possible and the higher measuring limit of the apparatus was reached.
The four measuring points do not form a function log p ~ 1/T, so a linear regression cannot be drawn. As a conservative result the vapour pressure for 25 °C is about 10-5 hPa or lower.
The vapour pressure value for 25 °C is lower than 10-5 hPa.

Description of key information
The vapour pressure value for 25 °C is lower than 10-5 hPa.
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 25 °C
Additional information
At 150 °C the measuring was stopped, because at higher temperatures a thermal decomposition of the test substance was possible and the higher measuring limit of the apparatus was reached.
The four measuring points do not form a function log p ~ 1/T, so a linear regression cannot be drawn. As a conservative result the vapour pressure for 25 °C is about 10-5hPa or lower.
The vapour pressure value for 25 °C is lower than 10-5hPa.
