The test item showed an endothermic signal in the temperature range of approx. 140 – 240 °C that can 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 5 (e.g. Benzyl alcohol). According to Hass & Newton a correction value φ = 5.75 was used for the temperature of 220 °C. The lowest measured onset temperature was corrected to the standard pressure to be 221.24 °C and the highest onset temperature to be 221.28 °C. As the corrected onset temperatures in both tests deviate less than 0.5 K from their mean value of 221.26 °C, the test item has a boiling point of 221.3 °C.

Conclusions:
The boiling point was determined to be 221.3 °C according to OECD 103.
Executive summary:

The test item has a boiling point of 221.3 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
