Conclusions:
Calculated vapour pressure at 20 °C 1.7 E-05 kPa and at 50 °C 6.7 E-04 kPa.
Executive summary:

The vapour pressure was measured with OECD 104 guideline method in a temperature range from 382.33 K to 574.07 K. To the experimental data Antoine parameters were fitted. Calculated values at 20 and 50 °C are given.
