Any other information on results incl. tables
The normal boiling temperature can be due to thermal decomposition of the test substance from284.7 °C not be determined.
According to the measured vapor pressure curve the boiling temperature at 30.06 hPa is 270.12 ° C. Results:| Temperature [t/°C] |

From 284.7 ° C (p = 50 hPa) the constant falling of ca. 6°C/min of the boiling temperature despite of increasing the heating power
and strong fog at the cooler shows a thermally induced change towards the test substance used. The normal boiling point can not be determined for this reason.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.
