Key result
Decomposition:
yes
Decomp. temp.:
240 °C
Remarks on result:
not determinable
Remarks:
No melting point was observed up to 240 °C. Over 240 °C the test item colour changed to brown and charred.

No melting point was observed up to 240 °C. Over 240 °C the test item colour changed to brown and charred. Therefore, it was concluded that the test item decomposed at 240°C before melting.

Conclusions:
The test item decomposed at 240°C before melting.
Executive summary:

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.

The test item decomposed at 240°C before melting.

Description of key information

The melting point of the test item was determined according to recognized guideline (EU Method A.1 and OECD guideline 102) and under GLP. No deviation from the guideline was observed during the test.

Key value for chemical safety assessment

Additional information

The test item decomposed at 240°C before melting. Indeed, the test item colour changed to brown and charred
