- Type of method:
- effusion method: Knudsen cell
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- Vapour pressure at 20 °C: 5.818 x 10 -7 Pa
Vapour pressure at 25 °C: 1.098 x 10 - 6 Pa - Executive summary:
Vapour pressure of the test item was determined using Vapor Pressure Analyzer (Knudsen Effusion Method) according to OECD guideline 104 and EU Method A.4. The study was conductec based on GLP-standards.
The following result was obtained:
Vapour pressure at 20 °C: 5.818 x 10 -7 Pa
Vapour pressure at 25 °C: 1.098 x 10 - 6 Pa
Reference
The vapour pressure was measured in the temperature range of 110 to 160 °C. For the evaluation the vapour pressure values in the range of 130 to 160 °C were used.
The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20 and 25 °C.
