Conclusions:
The boiling temperature of the substance has been determined to be: 226.4 °C at 1013.25 hPa.
Executive summary:

The boiling temperature was determined using EU Method A.2. and the Differential Scanning Calorimetry method. After determination of the melting point the test substance showed a second endothermic signal in the temperature range of 140 – 370 °C that can be associated with the boiling of the test substance. The lowest measured onset temperature is corrected to the standard pressure to be 226.4 °C and the highest onset temperature to be 226.4 °C. As the corrected onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 226.4 °C, the test item has a boiling point of 226.4 °C. No further thermal effects were observed up to the test end temperature of 500 °C. The boiling point of the test substance was determined to be 226.4 °C at 1013.25 hPa.

Additional information

Key data : EU Method A.2, 2015 : The boiling temperature was determined using EU Method A.2. and the Differential Scanning Calorimetry method. After determination of the melting point the test substance showed a second endothermic signal in the temperature range of 140 – 370 °C that can be associated with the boiling of the test substance. The lowest measured onset temperature is corrected to the standard pressure to be 226.4 °C and the highest onset temperature to be 226.4 °C. As the corrected onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 226.4 °C, the test item has a boiling point of 226.4 °C. No further thermal effects were observed up to the test end temperature of 500 °C. The boiling point of the test substance was determined to be 226.4 °C at 1013.25 hPa.
