Reference
The DSC-measurement in a closed glass crucible showed an exothermal decomposition in the temperature range of 230 - 365 °C with an energy of 986 J/g. Two DSC-runs in aluminium crucibles with a hole showed a broad endothermic effect in the temperature range of -115 to -75 °C (-140 to -50 °C) wit an onset temperature of -109 °C. The test item melts below - 50 °C.
Description of key information
- 50 °C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -50 °C
Additional information
GLP study according to OECD Guideline 102 (27 July 1995) and EU Method A.1 (30 May, 2008) using the differential scanning calorimetry.
