Table 1. Results of DSC Measurements

Sample	Sample weight / mg	Onset of Effect / °C	Range of effect / °C	Weight loss / mg	Atmospheric pressure / hPa
1	11.42	5.21 226.63	-10 to 30 (endo) 180 to 320 (endo)	11.42	1019.1
2	10.14	5.87 226.83	-10 to 30 (endo) 180 to 340 (endo)	9.92	1024.2

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.
