- 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 (DSC 25 -500 °C). 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 at atmospheric pressure of 431 °C.
Reference
The DSC measurements in aluminium crucibles with a hole showed endothermal effects in the
temperature range of 40 - 55 °C, 70 - 85 °C and 105 - 125 °C, followed by another endothermal effect
in the temperature range 400 - 460 °C.
