Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.:
ca. 25 °C
Vapour pressure:
< 0 Pa
Remarks on result:
other: Measurements made over the temperature range 160 to 213 degrees C. Weight displacement not detectable below 150 degrees C. Result at 25 degrees C by extrapolation (and less than the detection limit of the balance)

Applicant's summary and conclusion

Conclusions:
Vapour pressure at 25 degrees C is less than .00026 Pa by extrapolation (less than the detection limit of the balance)
