Any other information on results incl. tables

The vapour pressure was measured in the temperature range of 20 °C to 150 °C. In the temperature range 20 °C up to 106 °C no increase in weight and therefore no vapour pressure of the test substance was registered . Up to about 90 °C the test substance had melted, so the vapour pressure curve was restricted an the values between 1.1E-5 and 5.6E-4 hPa, i .e. between 112 °C and 150 °C. The values for 20, 25 and 50°C are calculated using the Antoine constants.

Applicant's summary and conclusion

Conclusions:
The extrapolated vapour pressure value for 25°C is 4.8E-11 hPa.
Executive summary:

Based on the measured data by using the effusion method (vapour pressure balance), the extrapolated vapour pressure value for 25°C is 4.8E-11 hPa.
