Description of key information
Several independent sources of information indicate that the boiling point is included in a range of 880°C – 883°C at 1013 hPa.
Considering a weight of evidence approach, an average value of 881.45°C at 101 325 Pa will be considered as a key value.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 881.45 °C
Additional information
Several independent and peer-reviewed sources of information indicate that the boiling point is included in a range of 880°C– 883°C at 1013 hPa.
The boiling point of the substance is reported to be 881.4°C (Merck Index, 2001), 883°C (Handbook of Chemistry and physics, 2002), 881.4°C (Sax, 1989), 880°C (Perry’s Chemical Engineer’s Handbook, 1988).
An average value of 881.45 °C will be considered in this dossier.
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.
