Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The boiling temperature of HMTBA was predicted by QSAR EPIWIN to be 290°C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 290 °C
Additional information
When heating the substance, a wide endotherm, ranging from 40 tocan be observed, followed by a markedly smaller endotherm ranging from 165 to. The first one is likely to correspond to components more volatile than water, to water itself (possibly affected by its salt and HMTBA content, it may boil and evaporate aboveat ambient pressure).
Also, a less energy-intensive endotherm can be observed between 165 and 210°C. This could correspond to non-esterified HMTBA.
The observation of several temperature ranges corresponding to distinct endothermic events between 40 and 210°C justify that the boiling point of HMTBA be evaluated by means of a QSAR.
The boiling temperature of HMTBA was predicted by QSAR EPIWIN to be 290°C.
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.
