Any other information on results incl. tables
The sudy was performed between 29.8 °C and 146.9 °C. The value at 29.8 °C was mot used for Antoine calculations because the quantification limit of the method. Therefore value of the vapour pressure of the test item at 20 °C was calculated by the mathematical extrapolation using the Antoine equation with ln p [kPa]= A-B/(T[]-C) where A = 17.0766, B = 4797.08 and C= 61.60. It was extrapolated to 0.3 hPa at 20 °C.
Applicant's summary and conclusion
- Conclusions:
- result of vapour pressure shows 0.3 hPa at 20 °C (by using the Antoine extrapolation)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
