Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
In run 1 the sample discoloured to yellow at 135°C, in run 2 discolouration was observed at 130.2°C.
The boiling point observed in this test is unexpectedly low in comparison with the melting range determined as part of EC Test A.1 (IUCLID section 4.2).
It is suspected that this may be due to the fact that the test material is a mixture. The components of the test material may have influenced the melting point and boiling point reversely. The components with higher melting points (longer chain lengths) may have a greater influence on the melting point whilst the components with a lower boiling point (shorter chain length) may have had a greater influence on the boiling point. Therefore the composition of the test material must be taken into consideration when interpreting the results.
Description of key information
The boiling point of the test substance was determined to be 126.4°C at atmospheric pressure in a GLP study according to EU method A.2 (Younis, 2013).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 126.4 °C
Additional information
The measured boiling temperature (126.5 °C) was obtained at 101.5 kPa and corrected to standard atmospheric pressure to 126.4 °C.
