Key result
Melting / freezing pt.:
> 400 °C
Decomposition:
ambiguous
Remarks on result:
other: No melting point was observed up to 400 ºC, but the colour of test item changed from initial yellow to firstly brown then black.

No melting point was observed up to 400 ºC, but the colour of test item changed from initial yellow to firstly brown then black.

Conclusions:
Under the conditions of the study no melting point was observed up to 400 ºC.
Executive summary:

The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions.

For the determination of the melting point or melting range, the capillary method was used. A small amount of the test item was heated in the electronic controlled sample block and the temperature around the sample was displayed. The sample was observed visually while raising the temperature. The initial and final melting temperatures were determined.

No melting point was observed up to 400 ºC, but the colour of the test item changed from initial yellow to firstly brown then black.

Description of key information

Under the conditions of the study, no melting point was observed up to 400 ºC.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
400 °C

Additional information

The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
