- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Measurement of vapour pressure with DSC (Differential Scanning Calorimetry) method.
- GLP compliance:
- not specified
- Type of method:
- other: differential scanning calorimetry (DSC)
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.011 Pa
- Remarks on result:
- other: The relationship between the pressure and the temperature was fitted with the Antoine model.
- Conclusions:
- At a temperature of 20 °C a vapour pressure of 0.010855 Pa was calculated for the test item.
- Executive summary:
The vapour pressure of the test item was measured at various temperatures with vacuum Differential Scanning Calorimetry (DSC). The vapour pressure of the test substance was measured in the temperature range of 56 - 88 °C. The relationship between the pressure and the temperature was fitted with the Antoine model. In the measured temperature range a vapour pressures between 56.1 and 89.6 mbar were calculated. The vapour pressure at 20 °C was calculated to be 0.010855 Pa.
