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
