In the temperature range of 90 to 100 °C a first endothermic effect could be observed. A second endothermic effect was detected in the temperature range of 320 to 390 °C. No further thermic effects could be observed up to the maximum temperature of 500 °C.

The test item showed a second endothermic signal in the temperature range of 320 – 390 °C, which could be assigned to the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 3 (e.g. Amines). A correction value φ = 5.55 was used for the temperature range from 350 °C to 360 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 351.56 °C and the highest onset temperature to be 355.86 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 353.71 °C, the test item has a boiling range from 351.6 °C to 355.9 °C.
No further thermal effects were observed up to the test end temperature of 500 °C
The boiling point of the test item was determined by Differential Scanning Calorimetry according to Regulation (EC) No 440/2008 Method A.2. and OECD Test Guideline 103 (1995). In the DSC measurement the first endothermic effect could be observed in the temperature range of 90 – 100 °C, which was followed by second endothermic effect in the temperature range of 320 – 390 °C. The second endothermic effect is assigned to the boiling point. The boiling point was corrected to standard pressure. The lowest measured onset temperature is corrected to the standard pressure to be 351.56 °C and the highest onset temperature to be 355.86 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 353.71 °C, the test item has a boiling range from 351.6 °C to 355.9 °C.
The corrected boiling range of the test item was determined to be from 351.6 °C to 355.9 °C at 1013 hPa (reference 4.3-2).
As supporting information the boiling point was described as 385 °C in a reliable data collection (reference 4.3-1).
