Vapeur pressures were calculated using a molar mass of 220.64 g/mol.
The regression of the vapour pressure data leads with a mean deviation of 9.3 % to the following results:
In (p/hPa) = 17.1677 -6784.90 / (T/K)
The vapour pressure at 20°C, 25 °C and 50°C was calculated from the regression equation.
P20°C 2.5 X 10 -3 hPa (extrapolated)
P25°C 3.7 x 10 -3 hPa (extrapolated)
P50°C 2.2 X 10 -2 hPa (interpolated)
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance is 0.0025 hPa at 20 °C, 0.0037 hPa at 25 °C and 0,022 hPa at 50 °C.
- Executive summary:
The vapour pressure of the substance is 0.0025 hPa at 20 °C, 0.0037 hPa at 25 °C and 0,022 hPa at 50 °C.
