| Calculated pressure: | < 0.1 | 20 | 3.411 |
* not used for test evaluation
Starting at approx. 290 °C decomposition occurred. Therefore, the last two measurements were not used for the test evaluation and no values could be taken during cooling-down process. The vapour pressure of the test item at 20 °C was calculated by mathematical extrapolation using the Antoine equation. It was calculated to < 0.1 hPa (at 20 °C).
Description of key information
The vapour pressure has been measured to be below < 0.1 hPa at 20 °C according to OECD TG104 and EU test method A.4 .
Key value for chemical safety assessment
- Vapour pressure:
- 0.1 hPa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of the test item has been determined in a GLP conform study according to OECD Guideline 104 and EU test method A.4 with the dynamic method. The vapour pressure has been measured to be below < 0.1 hPa at 20 °C.
