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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Melting/Freezing and Boiling Point
No endotherm relating to a melting temperature was observed, the melting point was therefore < -60°C. An exotherm followed by an endotherm was observed and a dark brown residue remained at the end of the test. This would suggest decomposition followed by boiling. The onset temperatures were 186°C for the exotherm and 320°C for the endotherm in test 1 and 193°C for the exotherm and to 320°C for the endotherm for test 2 This gave mean onset values of 189 and 320°C.
The DSC thermograms are shown in Figure 10 and Figure 11 (attached).
Description of key information
Study conducted to recognised testing guidelines and with GLP certification.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -60 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
