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 390 - 450 °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 %.

Conclusions:
The test items boiling range at atmospheric pressure was determined to be 411 - 413 °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 (DSC). The test item was weighed into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with 10 mg and 14 mg of the test item were performed. The crucible was heated from room temperature to 500 °C with 10 K/min heating rate. Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 390 - 450 °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 range of the test item at atmospheric pressure (1013.3 hPa) was determined to be 411 - 413 °C.

Description of key information
