Boiling point / boiling range: DSC measurement

Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 310 - 345 °C. The onset temperature 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 to 100 %.

Conclusions:
The boiling point of the test item was determined to be in a range of 326 - 329 °C.
Executive summary:

A study was conducted according to OECD TG 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 was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 15 – 16 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 310 - 345 °C. No further endothermic or exothermic effects were observed up to the final temperature (500 °C). The mass loss after the DSC measurements amounted to 100 %. The boiling point of the test item was determined to be in a range of 326 - 329 °C at 1013.3 hPa.
