OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
according to
Guideline:
other: VDI 2263 Part 1
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
differential thermal analysis (DTA)
Decomposition:
yes
Decomp. temp.:
189 - 427 °C

The heat of reaction recorded was -324 J/g (integration range 189 - 427 °C).

Conclusions:
The substance decomposes before melt.
Executive summary:

Differential Thermal Analysis (DTA) was assessed in accordance with VDI 2263 Part 1. The prepared sample was heated in a sealed glass ampoule at a heating rate of about 3 K/min. The sample temperature and the reference temperature (Al2O3) were recorded by computer system.

The heat of reaction recorded was -324 J/g (integration range 189 - 427 °C).

Conclusion

The substance decomposes before melting.

Description of key information

The substance decomposes before melting.

Key value for chemical safety assessment
