Key result
Atm. press.:
ca. 101.325 kPa
Decomposition:
yes
Decomp. temp.:
233.49 °C

A DSC curve was recorded during the experiment. A broad exothermic peak was observed caused by thermal degradation of the test substance. The onset temperature was 233°C. No boiling point was observed. On completion of testing a dark brown/black residue remained in the crucible.

Conclusions:
Under the conditions of this study, the boiling temperature of the test substance could not be determined because of thermal decomposition of the sample.
Executive summary:

The boiling point of the test material was investigated according to OECD method 103 using Differential Scanning Calorimetry.

A DSC curve was recorded. No boiling point peak was observed within a temperature range of 25°C - 500°C. A broad peak, with an onset temperature of 233°C was observed, caused by thermal degradation of the test substance.

Under the conditions of this study, the boiling temperature of the test substance could not be determined because of thermal decomposition of the sample

Description of key information

The boiling temperature of the test substance could not be determined because of thermal decomposition of the sample.

Key value for chemical safety assessment
