Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1998
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:

- Type of method:
- effusion method: vapour pressure balance
- Remarks:
- Knudson effusion method
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 30 °C
- Vapour pressure:
- 0 Pa
- Transition / decomposition:
- yes
- Transition temp.:
- 151.5 °C
- Conclusions:
- According to EU method A.4 a vapour pressure of 8.3 *10-6 Pa at 25°C was determined.
- Executive summary:
The temperature dependence of the vapour pressure of the test substance was detemined according EU method A.4 with the Knudsen effusion method using a vapour pressure balance in the temperature range 48 -98°C. The following vapour pressures were calculated for 20, 25 and 30°C using a semilogarithmic linear regression based on the Antoin equation to be: 4.1*10 -6 Pa, 8.3*10 -6 Pa and 1.6*10 -5 Pa, respectively.
