- Conclusions:
- Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C.
- Executive summary:
A study was conducted to determine the melting point of the substance according to OECD Guideline 102. To determine the melting behaviour (three independent single measurements), the test substance was measured by DSC between -90°C and 500°C with a heating / cooling rate of 10 K/min in 4 cycles. For the measurement a capsulated crucible was used. Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C (Kintrup, 2016).
Reference
Individual values:
225°C (from first measurement)
225°C (from second measurement)
224°C (from third measurement)
From 225°C the test substance showed most probably a thermal decomposition (a melting >225°C can't be excluded).
Description of key information
The melting point was determined according to OECD Guideline 102 (Kintrup, 2016)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 225 °C
Additional information
Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C.
