Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

B-TTEGME degrades prior to reaching the boiling point.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
385 °C

Additional information

The mixture B-TTEGME starts to evaporate at pressure of 984 hPa already at 50°C. The fastest weight loss was observed at ca. 385°C. This evaporation is accompanied with an exothermal event. A boiling would be reversible and accompanied with an endothermal event and therefore it is likely to be a decomposition. This observation was also confirmed in further experiments (DSC measurements). Due to this decomposition a boiling point for B-TTEGME cannot be determined.

For the further risk assessment, a boiling point of 385°C is assumed.
