Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The substance decomposes, starting at ca. 206 °C, in one study using DSC. The boiling temperature in another study using the Siwoloboff method was 236 °C. The boiling temperature, estimated by QSAR, is 426 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 426 °C
Additional information
The substance melted at 181 °C in a study using DSC. No further endothermal transitions were observed with the DSC-method at higher temperatures but an exothermal transition, a decomposition, was observed starting at 206 °C with a peak at 264 °C. The boiling temperature in another study using the Siwoloboff method was 236 °C. The discrepancy between the 2 methods could be explained by the decomposition of the substance in the same range, where a "boiling" was observed in the second study. But this "boiling" might well be a decomposition producing the gas bubbles observed in the Siwoloboff method. It is considered to be more likely that the substance decomposes above ca. 200 °C and that no boiling of the substance itself was observed. Therefore the calculated value was taken to characterize the boiling temperature.
The boiling temperature, estimated by QSAR, is 426 °C.
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).
