Description of key information

The vapour pressure of the substance was determined to be 0.224 hPa at 20°C, 0.335 hPa at 25 °C and 1.992 hPa at 50 °C.

Key value for chemical safety assessment

Vapour pressure:
0.224 hPa
at the temperature of:
20 °C

Additional information

Two studies were conducted. Both similar with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" by dynamic method. The vapour pressure was determined to be 0.224 hPa at 20 °C, 0.335 hPa at 25 °C and 1.992 hPa at 50 °C. An elder study determined the vapour pressure to be 1.95 hPa at 47.5 °C.


The results are in the same range an regarded to be reliable for the substance. The value from the most recent study was chosen as key value for the vapour pressure.
