Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Sep - Nov 1995
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point)
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
432 °C
Atm. press.:
101.3 kPa
Decomposition:
yes
Decomp. temp.:
> 182 °C
Remarks on result:
not determinable
Remarks:
calculated
Conclusions:
The DSC (Differential Scanning Calorimeter) analysis reveals a exothermic decomposition at temperatures higher than 182 °C. Therefore the boiling point cannot be measured but a theoretical value can be calculated with the datas from the vapour pressure measurement:
boiling point at 101.3 kPa: >182 °C (measured)
432 °C (calculated from vapour pressure measurement)

Description of key information

The DSC (Differential Scanning Calorimeter) analysis reveals a exothermic decomposition at temperatures higher than 182 °C.  Therefore the boiling point cannot be measured but a theoretical value can be calculated with the datas from the vapour pressure measurement:

      boiling point at 101.3 kPa:  >182 °C (measured)

                                                 432 °C (calculated from vapour pressure measurement)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
432 °C
