Key result
Atm. press.:
1 017 mBar
Decomposition:
yes
Decomp. temp.:
> 150 °C
Remarks on result:
other: Boiling point not determinable; test material decomposes at temperatures above approx. 150 °C before boiling

No endotherm associated with boiling was observed. There was significant departure from the baseline from approximately 150°C, followed by pronounced exotherms above 330°C, indicating decomposition. The decomposed sample had the appearance of a black solid at the end of testing.

Description of key information

Decomposes above approximately 150ºC without boiling (OECD 103, EU A.2)

Key value for chemical safety assessment

Additional information

Boiling point at 101700 Pa: > 150°C; decomposes before boiling
