Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No boiling point was determined between 25 °C and 400 °C as the decomposition of the test item happened between about 270 °C and 350 °C.
Key value for chemical safety assessment
Additional information
The determination of the boiling point/ boiling range of the test item was performed according to the EEC Directive 92/69, A.2 "Boiling temperature", December 1992 and to the OECD Guideline No. 103: "Boiling point", adopted July 27, 1995.
A preliminary test was performed in the temperature range between 25 °C and 400 °C. An endothermic heat effect was observed between 187 °C and 198 °C. This heat effect was due to the melting of the test item. Between about 270 °C and 350 °C an exothermic heat effect was observed, which is addressed to be the decomposition of the test item. After the preliminary test the test item was a black melt and had lost about 44 % of its mass.
To confirm the results of the preliminary test, two main tests between 150 °C and 250 °C with a heating rate of 10 K/min were performed. In both tests an endothermic heat effect, the melting, was observed between 185 °C and 191 °C. No heat effect, from which a boiling could be deducted, was observed below 250 °C. At the end of the test the test item was still coloured red and melted. The test item lost 0 %, 0.7 % of its mass respectively.
In conclusion, the test item does not boil under ambient conditions.
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.
