Results:

  • Single values: -24.9 °C ; -24.7 °C (closed crucible)
    -25.2 °C ; -24.9 °C (open crucible)
    The mean value of four measurements is -24.9 °C.
  • Exothermal decomposition started at 250 °C.
Conclusions:
The melting point was -24.9 °C (mean value). No pressure was reported.
Executive summary:

A differential thermal analysis (DTA)-system was used to determine the melting point which conforms with the procedure 'Test method A.1', described in the ECGuideline. Exothermal decomposition started at 250 °C. The melting point was -24.9 °C (mean value). No pressure was reported.

Description of key information

The melting point was -24.9 °C (mean value). No pressure was reported.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-24.9 °C
