Reference
two independent determinations. Results:
1. determination: 264 - 267 °C
2. determination: 263 - 268 °C
Observation:
Colour change to yellow at 263°C. Substance deepens continously in colour until turning brown/orange at 267°C.
Description of key information
No boiling point could be detected. Substance decomposed beginning at 260°C.
Key value for chemical safety assessment
