no

Two DSC measurements with a heating rate of 10 K/min showed neither an endothermal nor an exothermal effect after the melting (215 - 235 °C).

The test item had no boiling point up to 500 °C under atmospheric conditions.

The results of the DSC measurements are summarized in below table:

Additional information

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 500 °C under atmospheric conditions.
