Description of key information

No vapour pressure could be measured. The predicted vapour pressure of FAT 40841/A TE is extremely low and is assumed as close to zero in all calculations.

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

The vapour pressure of the substance cannot be determined experimentally. The vapour pressure may be predicted by using the boiling point predicted with Meissner's method (749 °C) and using the modified Watson correlation. The predicted vapour pressure would be extremely low. However, as the substance decomposes at or above 190 °C before it starts boiling, a vapour pressure based on a predicted boiling point >190 °C seems to be of little significance. A vapour pressure of close to zero is taken into account.
