The test item had no boiling point up to 400 °C under atmospheric conditions.

Conclusions:
The test item had no boiling point up to 400 °C under atmospheric conditions.
Executive summary:

A study was conducted according to OECD test guideline 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry.

The boiling point / boiling range was determined by differential scanning calorimetry (DSC). The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. The test item had no boiling point up to 400 °C under atmospheric conditions.

Description of key information

The test item had no boiling point up to 400 °C under atmospheric conditions.

Key value for chemical safety assessment
