Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The study has not been conducted according to a protocol to derive the melting point but has been sufficiently accurately measured while determining the thermal stability.
Qualifier:
according to guideline
Guideline:
other: OECD 113, screening test for thermal stability and stability in air
Qualifier:
according to guideline
Guideline:
other: VDI 2263: test methods for the determination of the safety charactersitics of dust, May 1981
Principles of method if other than guideline:
while determining the termal stability of the substance, melting point was determined
GLP compliance:
yes
Type of method:
thermal analysis
Melting / freezing pt.:
<= 230 °C
Remarks on result:
other: air atmosphere (DSC experiment)

While heating the substance to determine the thermal stbility, the sample appeared to have been molten and a chenge of colour at a temperature of 230 °C (503 K) in an air atmosphere (DSC experiment).

Conclusions:
After being heated to 230 °C the sample appeared to have molten.

Description of key information

While heating the substance to determine the thermal stbility, the sample appeared to have molten and changed colour at a temperature of 230 °C (503 K) in an air atmosphere (DSC experiment).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
230 °C
