Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Comparable to guideline study (EU A.1) with acceptable restrictions.
Principles of method if other than guideline:
Differential scanning calorimetry
Type of method:
thermal analysis
Melting / freezing pt.:
ca. 225 °C
Decomposition:
yes
Decomp. temp.:
ca. 245 °C
The product begins to melt at 225 °C (mean of 2 measurements). Exothermic decomposition starts at 245 °C (mean of 2 measurements). Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (1041 J/g; mean of 2 measurements) is less than the true decomposition energy.
Conclusions:
The product begins to melt at 225 °C (mean of 2 measurements).
Executive summary:

The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test item melts under decomposition starting from ca. 225 °C.
