Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressureopen allclose all
Temp.:
ca. 114 °C
Vapour pressure:
ca. 930 Pa
Temp.:
ca. 20 °C
Vapour pressure:
ca. 8.8 Pa
Remarks on result:
other: estimation based on liquid state
Transition / decomposition
Transition / decomposition:

Any other information on results incl. tables

Linear equation: log p = -2398.6*(1/T)+9.1268

Scope: from 114 to 180 °C

Nature of the change during measuring: none

Nature of the change for estimate: transition liquid-solid

Temperature of transition: 38.2 °C

Applicant's summary and conclusion

Conclusions:
The real value of vapour pressure for 20°C should be significantly low then the value estimated from vapor pressure curve for liquid. However the value could be used as worst case.
