Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting / freezing point
Key result
Melting / freezing pt.:
263 °C
Decomposition:
yes
Decomp. temp.:
>= 267 °C
Remarks on result:
other: See below

Any other information on results incl. tables

The product begins to melt at 263°C (onset of the endothermic process, taken as melting point). An exothermic decomposition starts at 267°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (918 J/g) is less than the true decomposition energy.

Applicant's summary and conclusion

Conclusions:
The test substances has a melting point of 263°C and starts to decompose at 267°C.

Executive summary:

The thermal behaviour of the test substance was determined with Differential Scanning Calorimetry (DSC) measurements. The melting point was 263°C and decomposition started at 267°C.
