Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Melting / freezing pt.:
- 70 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Conclusions:
- Melting of the test substance started at about 70"C (343 K). Probably reaction and or decomposition occurred at about 99°C - 105°C (372K- 378 K). The resultant more stable form of the test substance started to melt at about 120°C (393 K).
Reference
The performed experiments resulted in a lot of thermal.events, which are difficult to interpret.
Melting of the test substance started at about 70"C (343 K). Probably reaction and or decomposition occurred at about 99°C - 105°C (372K- 378 K). The resultant more stable form of the test substance started to melt at about 120°C (393 K). Boiling of the test substance was not observed. Reaction or decomposition of the test substance started in the region 120°C - 330°C (393 K- 603 K).
Description of key information
Melting of the test substance started at about 70"C (343 K). Probably reaction and or decomposition occurred at about 99°C - 105°C (372K- 378 K). The resultant more stable form of the test substance started to melt at about 120°C (393 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 70 °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.
