Description of key information
2.3E-07 hPa (20 °C) (EU A.4, effusion method, regression curve)
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure was extrapolated to be 2.3E-07 hPa at 20 °C. Actual vapour pressure of 1.5 x 10E-05 hPa could be measured at 63 °C.
