Conclusions:
The static method was applied for the determination of the vapour pressure of the test item. The vapour pressure of the test item was determined to be 15.6 hPa at 20°C.

Description of key information

The vapour pressure of the test substance was determined in a non GLP study to be 15.6 hPa at 20 °C, following the static technique (BASF AG, 1975).

Key value for chemical safety assessment

Vapour pressure:
15.6 hPa
at the temperature of:
