- Conclusions:
- Calculated vapour pressure at 20 °C 1.57 E-16 kPa and at 50 °C 1.64 E-13 kPa.
Values are afflicted with high relative uncertainties. - Executive summary:
The vapour pressure was measured with OECD 104 guideline method in a temperature range from 539.59 K to 595.19 K. To the experimental data Antoine parameters were fitted. Calculated values at 20 and 50 °C are given.
