Any other information on results incl. tables
Antoine constants for equation: log (p[hPa]) = A + B/(C + T[°C])
A = 8.13442
B = -2105.73
C = 273.15
Using these constants a vapour pressure of 8.9 hPa (20°C) can be calculated.
Applicant's summary and conclusion
- Conclusions:
- Based on the Antoine constants the vapour pressure of the test item is calculated to be 8.9 hPa at 20°C, 11.8 hPa at 25°C and 41.5 hPa at 50°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
