Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results:
Critical temperature: 719.9 +/- 1.0 K (= 446.75 +/- 1°C)
Critical density: 0.324 +/- 0.005 g/ml
A decrease of critical temperature with time, indicating thermal  decomposition, was observed but compensated using an extrapolation method.
