Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 220 °C
Additional information
There are seven published values available from handbooks or internet databases, all assessed with reliability 2, in the range of 219 -233°C, three of them confirmed to be measured at atmospheric pressure. Hence, it can be concluded that the other 4 values were only derived at atmospheric pressure, leading to the implication that the real value can be taken as 220°C at 760 Torr.
Further eight values are available in the temperature range of 68 -124°C, measured at a pressure of 2 -13 Torr (except one value with unknown pressure, which can be based on the other values available to be in th same pressure range). Since these low values are generally less relevant for risk assessment, where the usual atmospheric pressure of 1.013 bar is relevant, these values can so be regarded to a lesser extent, which is also applicable for the two values derived from QSAR estimation. Hence, 220°C at 760 Torr is left as the proper value for further risk assessment.
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.
