Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The optimal fit through the applied 9 data points is:

 

Ln P (P in mBar) = 21.481 – 7.8487 * 1000 / T (T in K)

 

The regression coefficient r = 0.979.
