Conclusions:
The test item had no boiling point at atmospheric conditions up to 500 'C.
Executive summary:

A study was conducted according to OECD test guideline 103, 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 10 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. In a defined atmosphere (nitrogen) the test item is heated up from ambient temperature to the final temperature (25 and 500 °C, respectively) at a constant heating rate (10 K/min). The quantity of heat absorbed or released is measured and recorded. The measurements in aluminium crucibles with a hole showed no endothermal effect up to 500 °C.

Description of key information

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

Key value for chemical safety assessment

Additional information

A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry (reference 4.3 -1). The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 12 -23 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. In a defined atmosphere (nitrogen) the test item is heated up from ambient temperature to the final temperature (150 and 500 °C, respectively) at a constant heating rate (10 K/min). The quantity of heat absorbed or released is measured and recorded. The measurements in aluminium crucibles with a hole showed no endothermal effect up to 500 °C.
