Reference
Run 1 was performed over a temperature range of 18.2 to 68.7°C. Run 2 was performed over a temperature range of 17.6 to 67.8°C. Vapour pressure curves were constructed (R²=0.9995 and 0.9991 for run 1 and run 2 respectively) and the vapour pressure at 20°C interpolated from the curves.
Description of key information
The vapour pressure of the test substance was determined in a GLP study according to test method EC A.4 to be 1306 Pa at 20 °C, following the isoteniscope method (Younis, 2013).
Key value for chemical safety assessment
- Vapour pressure:
- 1 306 Pa
- at the temperature of:
- 20 °C
