Reference
In the main tests, where the samples were heated up to 400 °C, bubbling started between 222-255 °C (mean value 246 °C, coefficient of variation 14.5, 95% confidence interval 12.2, n=8) . 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 251 °C, indicating decomposition.
Description of key information
> 246ºC (OECD 103, EU A.2)
Key value for chemical safety assessment
Additional information
Boiling point at 101 325 Pa > 246°C
The test material started darkening above 251 °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.
