During the heating phase a distinct endothermic effect was observed in the temperature range of 60 – 160 °C, which can be associated with the boiling point of the test item. The lowest measured onset temperature is corrected to standard pressure to be 99.17 °C and the highest to be 99.34 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 99.26 °C, the test item has a boiling point of 99.3 °C.

No further thermal effect were observed up to the maximum test temperature of 500°C.

Conclusions:
The test item has a boiling point of 99.3 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry.
Executive summary:

The test item has a boiling point of 99.3 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2., OECD Test Guideline 103 (1995).
