Reference
In the main tests, where the samples were heated up to 400 °C, bubbling started at around 160.5-164.9 °C (mean value 163 °C, coefficient of variation 2.0, 95% confidence interval 2.1, n=6). Due to the UVCB nature of the test material, bubbling was not continuously but occurred at intervals during the heating periods. The boiling point of the test material is given as the mean temperature above which the test material started showing boiling behaviour.
The test material was observed to darken from approximately 227-266 °C, indicating decomposition.
Description of key information
> 163 °C (OECD 103, EU A.2)
Key value for chemical safety assessment
Additional information
The test material was observed to darken from approx. 227 -266 °C, indicating decomposition. Due to the UVCB nature of the test material boiling was observed at intervals during heating periods. The boiling point of the test material is given as the mean temperature above which the test material started showing boiling behaviour.
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).
