Conclusions:
Under the test conditions, the average boiling point of the test material using DSC and ebulliometer techniques was determined to be 249.2 and 249.4 °C, respectively.
Executive summary:

A study was performed to determine the boiling point of the test material using DSC and ebulliometer techniques. The study was conducted according to OECD Guideline 103.

 

Duplicate runs were performed for the test substance and toluene was used as a reference to validate the test method. The experiments were stopped at 340 and 300 °C for the DSC and ebulliometer methods, respectively.

 

Under the test conditions, the average boiling point of the test material using DSC and ebulliometer techniques was determined to be 249.2 and 249.4 °C, respectively.

Description of key information

The boiling point was determined according to OECD Guideline 103 (Rivera, 2010).

Key value for chemical safety assessment
