Description of key information

The vapour pressure determined with the vapour pressure balance method was 1.35 x 10-9 hPa at 25°C (Bayer, 1992).

Key value for chemical safety assessment

Vapour pressure:
0 hPa
at the temperature of:
25 °C

Additional information

Gas saturation method delivered another result of <2.27 x 10-6 hPa at 25°C (Monsanto, 1980). Although this is about 1000 times higher than the one mentioned in key study, these two results are both far below 1 Pa indicating a very low vapour pressure.
