PRELIMINARY TEST

In case of the determination of the Melting Point of the test item (study code: 12/384-344AN) considered as preliminary test. The test item over 260 °C started to brown and by increasing the temperature the test item darkened, but stayed solid all over the measurement until 400 °C. No Melting Point was observed.

MAIN TEST

The test item has no melting point (study code: 12/384-344AN) therefore the samples in a glass tube were heated from 395°C with a rate of 0.5°C/min until 400 °C to. The colour of the test item was black. No boiling was observed.

Conclusions:

The substance showed signs of degradation from 260 °C. No boiling point was observed up to 400 °C.

Description of key information

The substance starts to degrade at 260 °C and showed no signs of boiling up to 400 °C.

Additional information

In a GLP study performed according to EU Method A.2 the substance did not boil at temperatures up to 400 °C. The substance started to degrade at temperatures > 260 °C.
