Description of key information

<0.0001 Pa at 25°C (measured)
2.34E-019 Pa at 25°C (calculated)

Key value for chemical safety assessment

Additional information

The measurement was carried out by effusion method, weight loss.

At the temperature applied the vapour pressure descended perpetually at constant temperature and reached the identification limit of the most sensitive measurement technique.

Additionally the vapour pressure of test substance was calculated based on Modified Grain Method using recommended MPBPVP (v1.43) module of software EPI Suite and yields a value of 2.34E-019 Pa at 25°C
