Two DSC measurements showed an endothermal effect after the melting in the temperature range of 360 - 415°C. The onset temperature (see Table 1) was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline. No further endothermic or exothermic effects were observed up to the final temperature (500°C). The mass loss after the DSC measurements amounted to100%.

The test item had a boiling point of 393.7°C after correction of the boiling point to standard atmospheric pressure (1013.3 hPa).

Conclusions:
The test item had a boiling point of 393.7 °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 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 a boiling point of 393.7 °C under atmospheric conditions.
