Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Remarks on result:
other: result by using the Antoine extrapolation

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)
