Measured melting point temperature:
1st: 180.1 °C
2nd: 180.8 °C
=> mean value: 180.5 °C.
At a temperature of approx. 210 °C the test item started to decompose. The decomposition was indicated by a short exothermal heat flow.
Description of key information
The melting point of the test item was determined according to EU A.1 and is 180.5 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 180.5 °C
Additional information
The result from the experimental study is supported by handbook data where a temperature range from 180 -190 °C is reported for the melting point of the test item.
