Results and discussion

Vapour pressure

Temp.:

25 °C

Vapour pressure:

< 0 Pa

Any other information on results incl. tables

The vapour pressure of the test substance at 25°C was estimated to be 1.43E-18 mmHg corresponding 1.91E-16 Pa (using the Modified Grain method). As the available experimental methods allow a determination of vapour pressures down to 10E-5 Pa only, no meaningful experimental determination of the vapour pressure of the test substance is possible. Therefore, in accordance to the respective EC guideline no experimental determination of the vapour pressure for the test substance is required.

Applicant's summary and conclusion

Conclusions:

A vapour pressure range was estimated to be < 10E-05 Pa by a well-established QSAR method.
