Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Vapour pressure
Temp.:
298 K
Vapour pressure:
0 kPa
Remarks on result:
other: maximum possible vapour pressure

Any other information on results incl. tables

Due to the low vapour pressure of the test item a calculation instead of a experimental determination was suitable.

The assessed melting point > 350°C is the basis for the calculation. A higher melting point results in a lower vapour pressure, therefore the calculation result can be regarded as valid.

Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item was calculated to be Pv = 1.45 * 10^(-10) Pa at 298K.
