Pre-test following Siwoloboff

The test item was heated until 400°C, without showing any signs of boiling or decomposition.

After cooling down the test item was visually like the original test item.

Conclusions:
In the DSC measurements no event was detected which could be a sign for boiling of the test item at temperatures up to 445°C.
Executive summary:

The determination of the boiling point study was performed using the DSC (differential scanning calorimetry). No signs of boiling could be observed in the pre-test according to Siwoloboff up to 400 °C.

In the DSC measurements no event was detected which could be a sign for boiling at temperatures up to 445°C.

No boiling point could be determined under these circumstances.

Therefore the boiling point should be stated as above 445°C.

Description of key information

The boiling point was determined according to OECD Guideline 103.

The determination of the boiling point study was performed using the DSC (differential scanning calorimetry). In the DSC measurements no event was detected which could be a sign for boiling at temperatures up to 445°C.

No boiling point could be determined under these circumstances.

Therefore the boiling point should be stated as above 445°C.

Key value for chemical safety assessment
