The thermograms show no clear sign of either boiling or degradation. This was confirmed by the presence of a residue in the crucibles similar in appearance to that of the test material. An investigative thermogram was carried out and taken up to 450°C. This

showed the start on an endotherm between 400°C and 450°C and was considered to be the start of the test material boiling.

Overall boiling point result: >673 ± 0.5 K

Conclusions:
The boiling point of the test material has been determined to be >673 ± 0.5 K (>400 ± 0.5°C) at 102.31 kPa.
Executive summary:

The study was conducted in order to determine the general physico-chemical properties of the test material. The boiling point of the test material has been determined to be >673 ± 0.5 K (>400 ± 0.5°C) at 102.31 kPa.

Description of key information

A key GLP study conducted in accordance with the OECD 103 guideline, boiling point= >673 ± 0.5 K (>400 ± 0.5°C) at 102.31 kPa

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
673 K

Additional information

A GLP compliant study conducted in accordance with the OECD 103 guideline, reported the boiling point of the test material to be >673 ± 0.5 K (>400 ± 0.5°C) at 102.31 kPa.
