Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Principles of method if other than guideline:
measurement by DSC
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Decomposition:
yes
Decomp. temp.:
> 311 °C

The product starts to decompose in the sealed vial at 311 °C with a mean energy of 334 J/g.

The minor exothermic process in the 246 - 304°C region may lead to a pressure lncrease in closed systems, if it is due to a partial decomposition.

Conclusions:
The test substance decomposed at >311°C.

Description of key information

Decomposed at >311°C without melting.

Key value for chemical safety assessment

Additional information

The determination was conducted by DSC with a heating rate of 3 K/min.
