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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Boiling point
- Key result
- Atm. press.:
- >= 1 002 - <= 1 007
- Decomposition:
- yes
- Decomp. temp.:
- >= 220 °C
- Remarks on result:
- other: Not detectable, because of thermal decomposition.
Any other information on results incl. tables
No thermal effect was observed up to 220 °C. In the temperature range of 220 °C up to 260 °C, an exothermic effect with an energy release of -360 J/g was detected. This effect was directly followed by a relatively broad endothermic signal in the temperature range of 260 °C up to 310 °C. Note that in both measurements more than 90 % of the sample got lost.

No melting or boiling of the test item was observed up to 220 °C where the test item started to undergo an exothermic effect.
Applicant's summary and conclusion
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.
