180 °C (DSC enthalpic change 2) Degradation

 

 

440°C (DSC enthalpic change 3) Degradation

Conclusions:
Under the study conditions, the boiling point could not be enstablised since the test substance starts to degrade above 180 °C (second transition). Full degradation happens at approx. 440 °C.
Executive summary:

A study was conducted to determine the boiling point of the test substance according to differential scanning calorimetry (DSC). The measurements were conducted at temperature program ranging from -60 °C to 500 °C with 10K/min. Under the study conditions, the boiling point could not be enstablised since the test substance starts to degrade above 180 °C (second transition). Full degradation happens at approx. 440 °C (Sohar, 2017).

Description of key information

The boiling point of was determined according to differential scanning calorimetry (DSC) (Sohar, 2017).

Key value for chemical safety assessment

Additional information
