Remarks on result:

other: measured by TGA

Boiling point determination according to Siwoloboff gave the following results:

Temperature and Observation:

ca..l90°C - sample returns yellow

ca. 285°C - sample returns brown

ca. 296 °C - sample returns dark brown

ca. 300 °C - sample returns black,

- evolution of gas bubbles, no boiling

k_p (98.3 kPa): >573 K

Conclusions:

The test substance decomposes at >190°C before boiling

Description of key information

The study provided was conducted to recognised testing guidelines and with GLP certification.

Additional information

decomposed before boiling (decomposition at >190°C)

The decomposition of substance was observed by determination according to Siwoloboff.

Additionally the boiling point of test substance was measured to be 131°C at 11 Pa by TGA and extrapolated to be 349°C at 1013 hPa
